Changelog for version 3.5-alpha7
--------------------------------
Since 3.5-alpha6
- Changed all #ifndef EXCLUDE_xx stuff to #ifdef CONFIG_xx. Modified
configure to handle this.
- Removed initialization messages from the
modularized version. They can be enabled by using init_trace=1 in
the insmod command line (insmod sound init_trace=1).
- More AIX stuff.
- Added support for syncronizing dsp/audio devices with /dev/sequencer.
- mmap() support for dsp/audio devices.
Since 3.5-alpha5
- AIX port.
- Changed some xxx_PATCH macros in soundcard.h to work with
big endian machines.
Since 3.5-alpha4
- Removed the 'setfx' stuff from the version distributed with kernel
sources.
Since 3.5-alpha3
- Moved stuff from the 'setfx' program to the AudioTriX Pro driver.
Since 3.5-alpha2
- Modifications to makefile and configure.c. Unnecessary sources
are no longer compiled. Newly created local.h is also copied to
/etc/soundconf. "make oldconfig" reads /etc/soundconf and produces
new local.h which is compatible with current version of the driver.
- Some fixes to the SB16 support.
- Fixed random protection fault in gus_wave.c
Since 3.5-alpha1
- Modified to work with Linux-1.3.33 and leater
- Some minor changes
Since 3.0.2
- Support for CS4232 based PnP cards (AcerMagic S23 etc).
- Full duplex support for some CS4231, CS4232 and AD1845 based cards
(GUA MAX, AudioTrix Pro, AcerMagic S23 and many MAD16/Mozart cards
having a codec mentioned above).
- Almost fully rewritten loadable modules support.
- Fixed some bugs.
- Huge amount of testing (more testing is still required).
- mmap() support (works with some cards). Requires much more testing.
- Sample/patch/program loading for TB Maui/Tropez. No initialization
since TB doesn't allow me to release that code.
- Using CS4231 compatible codecs as timer for /dev/music.
Since 3.0.1
- Added allocation of I/O ports, DMA channels and interrupts
to the initialization code. This may break modules support since
the driver may not free some resources on unload. Should be fixed soon.
Since 3.0
- Some important bug fixes.
- select() for /dev/dsp and /dev/audio (Linux only).
(To use select() with read, you have to call read() to start
the recording. Calling write() kills recording immediately so
use select() carefully when you are writing a half duplex app.
Full duplex mode is not implemented yet.) Select works also with
/dev/sequencer and /dev/music. Maybe with /dev/midi## too.
Since 3.0-beta2
- Minor fixes.
- Added Readme.cards
Since 3.0-beta1
- Minor fixes to the modules support.
- Eliminated call to sb_free_irq() in ad1848.c
- Rewritten MAD16&Mozart support (not tested with MAD16 Pro).
- Fix to DMA initialization of PSS cards.
- Some fixes to ad1848/cs42xx mixer support (GUS MAX, MSS, etc.)
- Fixed some bugs in the PSS driver which caused I/O errors with
the MSS mode (/dev/dsp).
Since 3.0-950506
- Recording with GUS MAX fixed. It works when the driver is configured
to use two DMA channels with GUS MAX (16 bit ones recommended).
Since 3.0-94xxxx
- Too many changes
Since 3.0-940818
- Fixes for Linux 1.1.4x.
- Disables Disney Sound System with SG NX Pro 16 (less noise).
Since 2.90-2
- Fixes to soundcard.h
- Non blocking mode to /dev/sequencer
- Experimental detection code for Ensoniq Soundscape.
Since 2.90
- Minor and major bug fixes
Since pre-3.0-940712
- GUS MAX support
- Partially working MSS/WSS support (could work with some cards).
- Hardware u-Law and A-Law support with AD1848/CS4248 and CS4231 codecs
(GUS MAX, GUS16, WSS etc). Hardware ADPCM is possible with GUS16 and
GUS MAX, but it doesn't work yet.
Since pre-3.0-940426
- AD1848/CS4248/CS4231 codec support (MSS, GUS MAX, Aztec, Orchid etc).
This codec chip is used in various soundcards. This version is developed
for the 16 bit daughtercard of GUS. It should work with other cards also
if the following requirements are met:
- The I/O, IRQ and DMA settings are jumper selectable or
the card is initialized by booting DOS before booting Linux (etc.).
- You add the IO, IRQ and DMA settings manually to the local.h.
(Just define GUS16_BASE, GUS16_IRQ and GUS16_DMA). Note that
the base address bust be the base address of the codec chip not the
card itself. For the GUS16 these are the same but most MSS compatible
cards have the codec located at card_base+4.
- Some minor changes
Since 2.5 (******* MAJOR REWRITE ***********)
This version is based on v2.3. I have tried to maintain two versions
together so that this one should have the same features than v2.5.
Something may still be missing. If you notice such things, please let me
know.
The Readme.v30 contains more details.
- /dev/midi## devices.
- /dev/sequencer2
Since 2.5-beta2
- Some fine tuning to the GUS v3.7 mixer code.
- Fixed speed limits for the plain SB (1.0 to 2.0).
Since 2.5-beta
- Fixed OPL-3 detection with SB. Caused problems with PAS16.
- GUS v3.7 mixer support.
Since 2.4
- Mixer support for Sound Galaxy NX Pro (define __SGNXPRO__ on your local.h).
- Fixed truncated sound on /dev/dsp when the device is closed.
- Linear volume mode for GUS
- Pitch bends larger than +/- 2 octaves.
- MIDI recording for SB and SB Pro. (Untested).
- Some other fixes.
- SB16 MIDI and DSP drivers only initialized if SB16 actually installed.
- Implemented better detection for OPL-3. This should be useful if you
have an old SB Pro (the non-OPL-3 one) or a SB 2.0 clone which has a OPL-3.
- SVR4.2 support by Ian Hartas. Initial ALPHA TEST version (untested).
Since 2.3b
- Fixed bug which made it impossible to make long recordings to disk.
Recording was not restarted after a buffer overflow situation.
- Limited mixer support for GUS.
- Numerous improvements to the GUS driver by Andrew Robinson. Including
some click removal etc.
Since 2.3
- Fixed some minor bugs in the SB16 driver.
Since 2.2b
- Full SB16 DSP support. 8/16 bit, mono/stereo
- The SCO and FreeBSD versions should be in sync now. There are some
problems with SB16 and GUS in the freebsd versions.
The DMA buffer allocation of the SCO version has been polished but
there could still be some problems. At least it hogs memory.
The DMA channel
configuration method used in the sco/System is a hack.
- Support for the MPU emulation of the SB16.
- Some big arrays are now allocated boot time. This makes the bss segment
smaller which makes it possible to use the full driver with
NetBSD. These arrays are not allocated if no suitable soundcard is available.
- Fixed a bug in the compute_and_set_volume in gus_wave.c
- Fixed the too fast mono playback problem of SB Pro and PAS16.
Since 2.2
- Stereo recording for SB Pro. Somehow it was missing and nobody
had noticed it earlier.
- Minor polishing.
- Interpreting of boot time arguments (sound=) for Linux.
- Breakup of sb_dsp.c. Parts of the code has been moved to
sb_mixer.c and sb_midi.c
Since 2.1
- Preliminary support for SB16.
- The SB16 mixer is supported in its native mode.
- Digitized voice capability up to 44.1 kHz/8 bit/mono
(16 bit and stereo support coming in the next release).
- Fixed some bugs in the digitized voice driver for PAS16.
- Proper initialization of the SB emulation of latest PAS16 models.
- Significantly improved /dev/dsp and /dev/audio support.
- Now supports half duplex mode. It's now possible to record and
playback without closing and reopening the device.
- It's possible to use smaller buffers than earlier. There is a new
ioctl(fd, SNDCTL_DSP_SUBDIVIDE, &n) where n should be 1, 2 or 4.
This call instructs the driver to use smaller buffers. The default
buffer size (0.5 to 1.0 seconds) is divided by n. Should be called
immediately after opening the device.
Since 2.0
Just cosmetic changes.

VoxWare v2.90 release notes
--------------------------
This version includes some hidden features which
are described in the file experimental.txt
Some of these features are not enabled by default. Look at
experimental.txt for more info.
I just decided to release this version with some
incompletely implemented features disabled since
there are some new features required by a popular
application. In addition there is also support
for the GUS MAX and the 16 bit sampling option of GUS.
The MSS/WSS support works now. At least with SG NX Pro 16.
********* IMPORTANT *****************************************
Linux 1.0 or later is required to by this driver version.
Don't distribute binaries which use /dev/sequencer and are
compiled with the soundcard.h of this version. They will
not work with version 2.x of the driver.
*************************************************************
You will need the snd-util-2.5.tar.gz and snd-data-0.1.tar.Z
packages to use this driver. They should be in the same
ftp site or BBS from where you got this driver. For
example at nic.funet.fi:pub/OS/Linux/*.
If you are looking for the installation instructions, please
look at linux/Readme.
Compatibility with the earlier versions
---------------------------------------
This version is backward compatible with the version 2.X. All programs
compiled with sys/soundcard.h of v2.X should work without problems.
PROGRAMS COMPILED WITH THE sys/soundcard.h OF THIS VERSION WILL NOT
WORK WITH v2.X DRIVER. BE CAREFUL WHEN DISTRIBUTING BINARIES COMPILED
FOR THIS VERSION.

GUSPNP15 8/6//97
ftp://rah.star-gate.com/pub/guspnp.tar.gz
This sound driver is for FreeBSD 3.0-current .
Major enhancement we now support mapping the dma buffer to user
space for write operations only. This features is useful for
games like xquake . So far the mmap features seems to work
with the GUS PnP Pro and with the SB16.
For xquake you will need:
1. a few mods to the linux loadable module so just download it and
replace yours:
cd /sys/i386/
tar -xzf linux_ioctl.tar.gz
cd /usr/src/lkm/linux
make
make install
modunload -i 0 (if you have the linux up and running)
linux
ftp://rah.star-gate.com/linux_ioctl.tar.gz
2. Install the linux lib 2.4 package:
pkg_add linux_lib-2.4.tgz
ftp://ftp.freebsd.org/pub/FreeBSD/packages-current/emulators/linux_lib-2.4.tgz
If you don't have xquake you can get it from:
3. ftp://ftp.freebsd.org/pub/idgames/idstuff/unsup/intel_linux_quake101.tgz
A simple test program mmap_test.c is provided in the sound driver directory.
So copy it to your home directory or favorite place and compile it.
cc -o mmap_test mmap_test.c
record a sample session:
cat /dev/dsp >smpl
now run mmap_test . You will hear a loud pop thats a test program
then the sample stream will loop .
Phew, now back to sound driver land 8)
This is a minor sound driver release for the GUS PnP Pro , GUS MAX,
AudioTrix Pro , SB16 and SB16 PnP. There is also an experimental
AWE sub model.
Included Luigi's clean up work . Tnks!
Randall Hopper's SB16 speed setting fix . Tnks!
Fixed signal handling throught out the sound driver. The problem
first surfaced with the SB16 not generating an interrupt on the
last dma request and SB afficionados quickly pointed out the
bug in the driver. I had to put back the auto dma feature for
xquake :(
NOTE YOU DON'T NEED THE PNP DRIVER FOR THE GUS PNP SINCE THE DRIVER
HAS BUILTIN PNP SUPPORT FOR THE GUS.
My P133 Bios supports PnP. To first figured out what my SB16 PnP
was being configured to I booted win95 and checked out what Win95
ended up with . Alternatively, if you want to you can also down
load Sujal Patel's PnP driver:
ftp://rah.start-gate.com/pub/FreeBSD-ISA_PnP_June8.tar.gz
follow the instructions on how to configure your PnP soundcard or
ISA device.
Lugi also has Sujal's PnP driver .
---
http://www.iet.unipi.it/~luigi/pnp.c
http://www.iet.unipi.it/~luigi/pnp.h
the two main files. Follow Sujal Patel's instructions
for installing pnp support.
http://www.iet.unipi.it/~luigi/pnpinfo.tgz
---
This is my kernel configuration for my SB16 PnP:
controller snd0
device sb0 at isa? port 0x220 irq 10 conflicts drq 3
device sbxvi0 at isa? port? irq? drq 5 conflicts
device opl0 at isa? port 0x388 conflicts
device sbmidi0 at isa? port 0x300 irq? conflicts
----
The difference between a GUS PnP and a GUS PnP PRO is that the Pro
comes with 512kb. I went out an got a 1mb 60ns 30pin simm and installed
it on my GUS PnP. I own a GUS PnP and a GUS PnP PRO.
To unpack:
cd /
mv /sys/i386/isa/sound /sys/i386/isa/sound.old
cd /sys/i386/isa/
tar -xzf guspnp15.tar.gz
cd /sys/i386/conf
Edit the kernel config file in /sys/i386/conf
IF YOU HAVE A GUS MAX or GUS add the option NOGUSPNP to the config file
OPTIONS NOGUSPNP
THEN follow the instructions for NONPNP CONFIGURATION
PNP CONFIGURATION
To configure your guspnp PRO if you have a motherboard which supports
PnP:
controller snd0
device gus0 at isa?
NONPNP CONFIGURATION
To configure your guspnp PRO if your motherboard does NOT support
PnP:
device gus0 at isa? port 0x220 irq 11 drq 1 flags 0x3
the gus pnp is fully software configurable and the above configuration
is setup for full duplex audio. The dma channel settings are:
drq 1 --- DMA channel for playback
flags 0x3 --- DMAN channel for recording
In the event that you have to configure a GUS PnP manually or a GUS MAX:
Available IRQs for the GUS are:
3, 5, 7, 9, 11, 12, 15
Available DMA channels for the GUS are:
1, 3, 5, 6, 7
config <kernel-file>
cd /sys/compile/<kernel-file>
make
make install
THERE IS NO NEED TO BOOT TO DOS TO CONFIGURE YOUR GUS PNP.
THE DRIVER HAS BUILTIN SUPPORT FOR PNP WHICH I GOT
FROM THE GRAVIS DRIVER DEVELOPMENT KIT
Many thanks to Brian Litzinger <brian@MediaCity.com> for
porting the sound driver 3.5 to 2.2-current. Well, thats a while
ago hence the reference to 2.2.
Have fun,
Amancio

VoxWare v3.5-alpha5 release notes
---------------------------------
IMPORTANT! This version of the driver is compatible only with Linux versions
1.3.33 and later. It may work with earlier ones as a loadable
module but...
Also this is an ALPHA test version which has not been tested
with all cards. At least AEDSP16 support will not work. PAS16
and PSS supports have not been tested. /dev/dsp and /dev/audio
playback with standard GUS sounds scrambled. 16 bit mode of
SB16 doesn't work.
Please read the SOUND-HOWTO (available from sunsite.unc.edu and other Linux ftp
sites). It contains much more information than this file.
*****************************************************************
* NEW! VoxWare home page is http://personal.eunet.fi/pp/voxware *
* The file Readme.cards contains card specific instructions *
* about configuring various cards. *
*****************************************************************
There are some programming information (little bit old) in the
Hacker's Guide
(ftp://nic.funet.fi/pub/OS/Linux/ALPHA/sound/snd-sdk-doc-0.1.ps.gz).
Believe me: The file is really there. The directory is just hidden and
you have to cd into it before the file is visible. Note: This directory
was accidently removed some time ago but it's now back.
I have got many patches from various persons during last year. Some of
them are still on my mailbox and they should be included in versions
after v3.0 (I will not add aditional features before v3.0 is ready).
====================================================
- THIS VERSION ____REQUIRES____ Linux 1.3.33 OR LATER.
====================================================
- THIS VERSION MAY NOT WORK WITH Linux VERSIONS RELEASED
AFTER end of Nov 1995. If this version doesn't compile with
your kernel version, please use the sound driver version
included in your kernel.
You will need the snd-util-3.0.tar.gz and snd-data-0.1.tar.Z
packages to use this driver. They should be in the same
ftp site or BBS from where you got this driver. For
example at nic.funet.fi:pub/OS/Linux/*.
If you are looking for the installation instructions, please
look at linux/Readme.
Supported soundcards
--------------------
Gravis Ultrasound (GUS)
GUS MAX
GUS with the 16 bit sampling daughtercard
PAS16
Windows Sound System compatible soundcards
ECHO-PSS (cards based on the PSS architecture by Analog Devices.
Including Orchid SW32, Cardinal DSP16 among others).
(NOTE! WSS mode may not work (DMA channel setup problem)).
MediaTriX AudioTriX Pro (OPL4 and the optional effect daughtercard
require special initialization. There is a program (setfx) in
the snd-util-3.0.tar.gz package which does it).
Ensoniq SoundScape (works but needs some improvements)
MV Jazz16 based soundcards (ProSonic, 3D etc).
SoundMan Wave (recording may not work, mixer support is limited)
Mozart (OAK OTI-601 interface chip) based soundcards.
MAD16 (an interface chip by OPTi) based soundcards (TB Tropez ???).
(NOTE! The MAD16 looks similar to the Mozart chip. It could be a good
idea to configure MAD16 cards as Mozart ones. The MAD16 driver doesn't set
up MPU401 which the Mozart one does.
CS4232 based cards such as AcerMagic S23.
In addition all Sound Blaster models and clones (up to AWE32) work if
you want to use them.
The Emu synthesizer chip of AWE32 is not and will not be supported. The same is
true with the ASP chip also. Creative Technology will not release detailed
information about them so it's not possible to support them.
If you want to get support for AWE32 or ASP, please contact Creative Labs.
Ask _politely_ if they are going to support Linux. Maybe they change
their policy if there is enough demand.
===========================================================================
If your card is compatible with SB, MPU401 or Windows Sound System, it
may work with the driver even if it's not listed in the above list. In this
case it may require initialization using DOS. Just start DOS and cold
boot to Linux (etc.) by hitting ctrl-alt-del.
===========================================================================
Compatibility with the earlier versions
---------------------------------------
There have been some changes in soundcard.h after v2.5 of the driver
(v2.90 is compatible with this one). Binaries compiled with this version
of soundcard.h will not work with v2.0 and earlier.

If you have some problems
=========================
Read the sound HOWTO (sunsite.unc.edu:/pub/Linux/docs/...?).
Also look at the home page (http://personal.eunet.fi/pp/voxware). It may
contain info about some recent bug fixes.
It's likely that you have some problems when trying to use the sound driver
first time. Soundcards don't have standard configuration so there are no
good default configuration to use. Please try to use same I/O, DMA and IRQ
values for the soundcard than with DOS.
If you get an error message when trying to use the driver, please look
at /var/adm/messages for more verbose error message.
In general the easiest way to diagnoze problems is to do "cat /dev/sndstat".
If you get an error message, there are some problems with the driver setup:
- "No such file or directory" tells that the device files for
the sound driver are missing. Use the script at the end of
linux/drivers/sound/Readme.linux to create them.
- "No such device" telss that the sound driver is not in the kernel.
You have to reconfigure and recompile the kernel to have the sound
driver. Compiling the driver doesn't help alone. You have to boot
with the newly compiled one before the driver becomes active.
The Linux-HOWTO should help in this step.
The following errors are likely with /dev/dsp and /dev/audio.
- "No such device or address". This error message should not happen
with /dev/sndstat but it's possible with the other sound devices.
This error indicates that there are no suitable hardware for the
device file or the sound driver has been compiled without support for
this particular device. For example /dev/audio and /dev/dsp will not
work if "digitized voice support" was not enabled during "make config".
- "Device or resource busy". Propably the IRQ (or DMA) channel
required by the soundcard is in use by some other device/driver.
- "I/O error". Almost certainly (99%) it's an IRQ or DMA conflict.
Look at the kernel messages in /var/adm/notice for more info.
- "Invalid argument". The application is calling ioctl()
with impossible parameters. Check that the application is
for sound driver version 2.X or later.
In general the printout of of /dev/sndstat should tell what is the problem.
It's possible that there are bugs in the sound driver but 99% of the problems
reported to me are caused by somehow incorrect setup during "make config".
For owners of TI TM4000M notebooks
----------------------------------
There appears to be some kind of conflict between the sound support
(MV Jazz), mouse port and VoxWare. You could try to configure kernel
with the C&T 82C710 mouse port support disabled.

Configuring VoxWare 3.0 (for Linux) with some most common soundcards
====================================================================
NOTE! This document may contain some error. Please inform me
if you find any mistakes.
Read this before trying to configure the driver
-----------------------------------------------
There are currently many cards that work with VoxWare. Some of the cards
have native support while the others work since they emulate some other
cards (usually SB, MSS/WSS and/or MPU401). The following cards have native
support in VoxWare. Detailed instructions for configuring these cards
will be given later in this document.
Pro Audio Spectrum 16 (PAS16) and compatibles:
Pro Audio Spectrum 16
Pro Audio Studio 16
Logitech Sound Man 16
NOTE! The original Pro Audio Spectrum as well as the PAS+ are not
and will not be supported by VoxWare.
Media Vision Jazz16 based cards
Pro Sonic 16
Logitech SoundMan Wave
(Other Jazz based cards should work but I don't have any reports
about them).
Sound Blasters
SB 1.0 to 2.0
SB Pro
SB 16
NOTE! The ASP chip and the EMU synth of the AWE32 is not supported
since their manufacturer doesn't release information about
the card. However both the AB16ASP and the AWE32 work with
VoxWare just like a SB16. Also see the comment about some
unsupported cards at the end of this file.
SB16 compatible cards by other manufacturers than Creative.
You have been fooled since there are no SB16 compatible
cards in the market (July95). It's likely that your card
is compatible just with SB Pro but there is also a non SB
compatible 16 bit mode. Usually it's MSS/WSS but could also
be a proprietary one like MV Jazz16.
Gravis Ultrasound (GUS)
GUS
GUS + the 16 bit option
GUS MAX
GUS ACE (No MIDI port and audio recording)
MPU-401 and compatibles
The driver works both with the full (intelligent mode) MPU-401
cards (such as MPU IPC-T and MQX-32M) and with the UART only
dumb MIDI ports. MPU-401 is currently the most common MIDI
interface. Most soundcards are compatible with it. However
don't enable MPU401 mode blindly. Many cards having native support
in VoxWare have their own MPU401 driver. Enabling the standard one
will cause a conflict with these cards. So look if your card is
in the list of supported cards before enabling MPU401.
Windows Sound System (MSS/WSS)
Even Microsoft has discontinued their own Sound System card, they
managed to make a standard. MSS compatible cards are based on a
codec chip which is easily available from at least two manufacturers
(AD1848 by Analog Devices and CS4231/CS4248 by Crystal Semiconductor).
Currently most soundcards are based on one of the MSS compatible codec
chip. The CS4231 is used in the high quality cards such as GUS MAX,
MediaTriX AudioTriX Pro and TB Tropez (GUS MAX is not MSS compatible).
Having a AD1848, CS4248 or CS4231 codec chip on the card is a good
sign. Even if the card is not MSS compatible, it could be easy to write
support for it to VoxWare. Note also that most MSS compatible cards
require special boot time initialization which may not be present
in VoxWare. Also some MSS compatible cards have native support in
VoxWare. Enabling the MSS support with these cards is likely to
cause a conflict. So check if your card is listed in this file before
enabling the MSS support.
6850 UART MIDI
This UART chip is used in the MIDI interface of some (rare)
soundcards. It's supported by VoxWare in case you need it.
Yamaha FM synthesizers (OPL2, OPL3 and OPL4)
Most soundcards have a FM synthesizer chip. The OPL2 is a 2
operator chip used in the original AdLib card. Currently it's used
only in the cheapest (8 bit mono) cards. The OPL3 is a 4 operator
FM chip which provides better sound quality and/or more available
voices than the OPL2. The OPL4 is a new chip which has a OPL3 and
a wave table synthesizer packed on the same chip. VoxWare supports
just the OPL3 mode directly. Most cards having a OPL4 (like
SM Wave and AudioTriX Pro) support the OPL4 mode using MPU401
emulation. Writing a native OPL4 support to VoxWare is difficult
since Yamaha doesn't give information about their sample ROM chip.
Enable the generic OPL2/OPL3 FM synthesizer support if your
card has a FM chip made by Yamaha. Don't enable it if your card
has a software (TRS) based FM emulator.
PSS based cards (AD1848 + ADSP-2115 + Echo ESC614 ASIC)
Analog Devices and Echo Speech have together defined a soundcard
architecture based on the above chips. The DSP chip is used
for emulation of SB Pro, FM and General MIDI/MT32.
There are several cards based on this architecture. The most known
ones are Orchid SW32 and Cardinal DSP16.
VoxWare supports downloading DSP algorithms to these cards.
MediaTriX AudioTriX Pro
The ATP card is built around a CS4231 codec and a OPL4 synthesizer
chips. The OPL4 mode is supported by a microcontroller running a
General MIDI emulator. There is also a SB 1.5 compatible playback mode.
Ensoniq SoundScape and compatibles
Ensoniq has designed a soundcard architecture based on the
OTTO synthesizer chip used in their professional MIDI synthesizers.
Several companies (including Ensoniq, Reveal and Spea) are selling
cards based on this architecture.
MAD16 and Mozart based cards
The Mozart (OAK OTI-601) and MAD16 Pro (OPTi 82C929) interface
chips are used in many different soundcards, including some
cards by Reveal and Turtle Beach (Tropez). Purpose of these
chips is to connect other audio components to the PC bus. The
interface chip performs address decoding for the other chips.
Audio Excell DSP16
Support for this card is made by Riccardo Faccetti
(riccardo@cdc8g5.cdc.polimi.it). See aedsp16.c for more info.
Crystal CS4232 based cards such as AcerMagic S23
CS4232 is a PnP multimedia chip which contains a CS3231A codec,
SB and MPU401 emulations. There is support for OPL3 too.
(Unfortunately the MPU401 mode doesn't work).
Turtle Beach Maui and Tropez
VoxWare supports sample, parch and program loading commands
described in the Maui/Tropez User's manual. There is no initialization
code for Maui so it must be initialized using DOS. Audio side of Tropez
is based on the MAD16 chip (see above).
Jumpers and software configuration
----------------------------------
Some of the earliest soundcards were jumper configurable. You have to
configure VoxWare to configure VoxWare use I/O, IRQ and DMA settings
that match the jumpers. Just few 8 bit cards are fully jumper
configurable (SB 1.x/2.x, SB Pro and clones).
Some cards made by Aztech have an EEPROM which contains the
config info. These cards behave much like hardware jumpered cards.
Most cards have jumper for the base I/O address but other parameters
are software configurable. Sometimes there are few other jumpers too.
Latest cards are fully software configurable or they are PnP ISA
compatible. There are no jumpers on the board.
VoxWare handles software configurable cards automaticly. Just configure
the driver to use I/O, IRQ and DMA settings which are known to work.
You could usually use the same values than with DOS and/or Windows.
Using different settings is possible but not recommended since it may cause
some trouble (for example when warm booting from an OS to another or
when installing new hardware to the machine).
VoxWare sets the soft configurable parameters of the card automaticly
during boot. Usually you don't need to run any extra initialization
programs when booting Linux but there are some exceptions. See the
card specific instructions (below) for more info.
The drawback of software configuration is that the driver needs to know
how the card must be initialized. It cannot initialize unknown cards
even if they are otherwise compatible with some other cards (like SB,
MPU401 or Windows Sound System).
What if your card was not listed above?
---------------------------------------
The first thing to do is to look at the major IC chips on the card.
Many of the latest soundcards are based on some standard chips. If you
are lucky, all of them could be supported by VoxWare. The most common ones
are the OPTi MAD16, Mozart, SoundScape (Ensoniq) and the PSS architectures
listed above. Also look at the end of this file for list of unsupported
cards and the ones which could be supported later.
The last resort is to send _exact_ name and model information of the card
to me together with a list of the major IC chips (manufactured, model) to
me. I could then try to check if your card looks like something familiar.
There are much more cards in the word than listed above. The first thing to
do with these cards is to check if they emulate some other card/interface
such as SB, MSS and/or MPU401. In this case there is a chance to get the
card to work by booting DOS before starting Linux (boot DOS, hit ctrl-alt-del
and boot Linux without hard resetting the machine). In this method the
DOS based driver initializes the hardware to use a known I/O, IRQ and DMA
settings. If VoxWare is configured to use the same settings, everything should
work OK.
Configuring VoxWare (with Linux)
================================
VoxWare sound driver is currently a part of Linux kernel distribution. The
driver files are located in directory /usr/src/linux/drivers/sound.
****************************************************************************
* VoxWare MUST BE CONFIGURED AND COMPILED WITH THE KERNEL. TRYING *
* TO COMPILE IT ALONE WILL _NOT_ WORK. *
* *
* ALWAYS USE THE SOUND DRIVER VERSION WHICH IS DISTRIBUTED WITH *
* THE KERNEL SOURCE PACKAGE YOU ARE USING. SOME ALPHA AND BETA TEST *
* VERSIONS CAN BE INSTALLED FROM A SEPARATELY DISTRIBUTED PACKAGE *
* BUT CHECK THAT THE PACKAGE IS NOT MUCH OLDER (OR NEWER) THAN THE *
* KERNEL YOU ARE USING. IT'S POSSIBLE THAT THE KERNEL/DRIVER *
* INTERFACE CHANGES BETWEEN KERNEL RELEASES WHICH MAY CAUSE SOME *
* INCOMPATIBILITY PROBLEMS. *
* *
* IN CASE YOU INSTALL A SEPARATELY DISTRIBUTED SOUND DRIVER VERSION, *
* BE SURE TO REMOVE OR RENAME THE OLD SOUND DRIVER DIRECTORY BEFORE *
* INSTALLING THE NEW ONE. LEAVING OLD FILES TO THE SOUND DRIVER *
* DIRECTORY _WILL_ CAUSE PROBLEMS WHEN THE DRIVER IS USED OR *
* COMPILED. *
****************************************************************************
To configure the driver, run "make config" in the kernel source directory
(/usr/src/linux). Answer y to the question about Sound card support (after
questions about mouse, CD-ROM, ftape, etc. supports). Sound config options
will then be asked after some additional questions.
After configuring the kernel and sound driver, run "make dep" and compile
the kernel following instructions in the kernel README.
The sound driver configuration dialog
-------------------------------------
All config information of the sound driver is written to file
linux/drivers/sound/local.h. You may save the old version is this file and
use it again in case you want to use the same config later. In this case
just answer n to each question made by the sound config program and put
the original local.h back before running "make dep".
Don't do this if the version number of the sound driver has changed. In this
case you have to enter the configuration information again.
If you already have the sound driver installed, consult printout of
"cat /dev/sndstat" when configuring the driver again. It gives the I/O,
IRQ and DMA settings you have used earlier.
The sound config program (linux/drivers/sound/configure) starts by making
some yes/no questions. Be careful when answering to these questions since
answering y to a question may prevent some later ones from being asked. For
example don't answer y to the first question (PAS16) if you don't really
have a PAS16. Don't enable more cards than you really need since they
just consume memory. Also some drivers (like MPU401) may conflict with your
SCSI controller and prevent kernel from booting. If you card was in the list
of supported cards (above), please look at the card specific config
instructions (later in this file) before starting to configure. Some cards
must be configured in way which is not obvious.
So here is the beginning of the config dialog. Answer 'y' or 'n' to these
questions. The default answer is shown so that (y/n) means 'y' by default and
(n/y) means 'n'. To use the default value, just hit ENTER. But be careful
since using the default _doesn't_ guarantee anything.
Note also that all questions may not be asked. The configuration program
may disable some questions dependig on the earlier choices. It may also
select some options automaticly as well.
"ProAudioSpectrum 16 support",
- Answer 'y'_ONLY_ if you have a Pro Audio Spectrum _16_,
ProAudio Studio 16 or Logitech SoundMan 16 (be sure that
you read the above list correctly). Don't answer 'y' if you
have some other card made by Media Vision or Logitech since they
are not PAS16 compatible.
"SoundBlaster support",
- Answer 'y' if you have an original SB card made by Creative Labs
or a full 100% hardware compatible clone (like Thunderboard or
SM Games). If your card was in the list of supported cards (above),
please look at the card specific instructions later in this file
before answering this question. For an unknown card you may answer
'y' if the card claims to be SB compatible.
Don't enable SB if you have a MAD16 or Mozart compatible card.
"Generic OPL2/OPL3 FM synthesizer support",
- Answer 'y' if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4).
Answering 'y' is usually a safe and recommended choice. However some
cards may have software (TSR) FM emulation. Enabling FM support
with these cards may cause trouble. However I don't currently know
such cards.
"Gravis Ultrasound support",
- Answer 'y' if you have GUS or GUS MAX. Answer 'n' if you don't
have GUS since the GUS driver consumes much memory.
Currently I don't have experiences with the GUS ACE so I don't
know what to answer with it.
"MPU-401 support (NOT for SB16)",
- Be careful with this question. The MPU401 interface is supported
by almost any soundcard today. However some natively supported cards
have their own driver for MPU401. Enabling the MPU401 option with
these cards wil cause a conflict. Also enabling MPU401 on a system
that doesn't really have a MPU401 could cause some trouble. If your
card was in the list of supported cards (above), please look at
the card specific instructions later in this file.
It's safe to answer 'y' if you have a true MPU401 MIDI interface
card.
"6850 UART Midi support",
- It's safe to answer 'n' to this question in all cases. The 6850
UART interface is so rarely used.
"PSS (ECHO-ADI2111) support",
- Answer 'y' only if you have Orchid SW32, Cardinal DSP16 or some
other card based on the PSS chipset (AD1848 codec + ADSP-2115
DSP chip + Echo ESC614 ASIC CHIP).
"16 bit sampling option of GUS (_NOT_ GUS MAX)",
- Answer 'y' if you have installed the 16 bit sampling daughtercard
to your GUS. Answer 'n' if you have GUS MAX. Enabling this option
disables GUS MAX support.
"GUS MAX support",
- Answer 'y' only if you have a GUS MAX.
"Microsoft Sound System support",
- Again think carefully before answering 'y' to this question. It's
safe to answer 'y' in case you have the original Windows Sound
System card made by Microsoft or Aztech SG 16 Pro (or NX16 Pro).
Also you may answer 'y' in case your card was not listed earlier
in this file. For cards having native support in VoxWare, consult
the card specific instructions later in this file. Some drivers
have their own MSS support and enabling this option wil cause a
conflict.
"Ensoniq Soundscape support",
- Answer 'y' if you have a soundcard based on the Ensoniq SoundScape
chipset. Suach cards are being manufactured at least by Ensoniq,
Spea and Reveal (note that Reveal makes other cards also).
"MediaTriX AudioTriX Pro support",
- Answer 'y' if you have the AudioTriX Pro.
"Support for MAD16 and/or Mozart based cards",
- Answer y if your card has a Mozart (OAK OTI-601) or MAD16
(OPTi 82C928 or 82C929) audio interface chip. These chips are
currently quite common so it's possible that many no-name cards
have one of them. In addition the MAD16 chip is used in some
cards made by known manufacturers such as Turtle Beach (Tropez),
Reveal (some models) and Diamond (latest ones).
"SoundBlaster Pro support",
- Enable this option if your card is SB Pro or SB16. Enable it
also with any SB Pro clones. Answering 'n' saves some amount of
memory but 'y' is the safe alterative.
"SoundBlaster 16 support",
- Enable if you have a SB16 (including the AWE32).
"Audio Excel DSP 16 initialization support",
- Don't know much about this card. Look at aedsp16.c for more info.
Then the configuration program asks some y/n questions about the higher
level services. It's recommended to answer 'y' to each of these questions.
Answer 'n' only if you know you will not need the option.
"/dev/dsp and /dev/audio supports (usually required)",
- Answering 'n' disables /dev/dsp and /dev/audio. Answer 'y'.
"MIDI interface support",
- Answering 'n' disables /dev/midi## devices and access to any
MIDI ports using /dev/sequencer and /dev/music. This option
also affects any MPU401 and/or General MIDI compatible devices.
"FM synthesizer (YM3812/OPL-3) support",
- Answer 'y' here.
"/dev/sequencer support",
- Answering 'n' disables /dev/sequencer and /dev/music.
Entering the I/O, IRQ and DMA config parameters
-----------------------------------------------
After the above questions the configuration program prompts for the
card specific configuration information. Usually just a set of
I/O address, IRQ and DMA numbers are asked. With some cards the program
asks for some files to be used during initialization of the card. For example
many cards have a DSP chip or microprocessor which must be initialized by
downloading a program (microcode) file to the card. In some cases this file
is written to a .h file by the config program and then included to the driver
during compile.
Instructions for answering these questions are given in the next section.
Card specific information
=========================
This section gives additional instructions about configuring some cards.
Please refer manual of your card for valid I/O, IRQ and DMA numbers. Using
the same settings with DOS/Windows and VoxWare is recommended. Using
different values could cause some problems when switching between
different operating systems.
SoundBlasters (the original ones by Creative)
---------------------------------------------
It's possible to configure these cards to use different I/O, IRQ and
DMA settings. Since the available settings have changed between various
models, you have to consult manual of your card for the proper ones. It's
a good idea to use the same values than with DOS/Windows. With SB and SB Pro
it's the only choice. SB16 has software selectable IRQ and DMA channels but
using different values with DOS and Linux is likely to cause troubles. The
DOS driver is not able to reset the card properly after warm boot from Linux
if Linux has used different IRQ or DMA values.
The original (steam) Sound Blaster (versions 1.x and 2.x) use always
DMA1. There is no way to change it.
The SB16 needs two DMA channels. A 8 bit one (1 or 3) is required for
8 bit operation and a 16 bit one (5, 6 or 7) for the 16 bit mode. In theory
it's possible to use just one (8 bit) DMA channel by answering the 8 bit
one when the configuration program asks for the 16 bit one. This may work
in some systems but is likely to cause terrible noise on some other systems.
NOTE! Don't enable the SM Games option (asked by the configuration program)
if you are not 101% sure that your card is a Logitech Soundman Games
(not a SM Wave or SM16).
SB Clones
---------
First of all: There are no SB16 clones. There are SB Pro clones with a
16 bit mode which is not SB16 compatible. The most likely alternative is that
the 16 bit mode means MSS/WSS.
There are just few fully 100% hardware SB or SB Pro compatible cards.
I know just Thunderboard and SM Games. Other cards require some kind of
hardware initialization before they become SB compatible. Check if your card
was listed in the beginning of this file. In this case you should follow
instructions for your card later in this file.
For other not fully SB clones yoy may try initialization using DOS in
the following way:
- Boot DOS so that the card specific driver gets run.
- Hit ctrl-alt-del (or use loadlin) to boot Linux. Don't
switch off power or press the reset button.
- If you use the same I/O, IRQ and DMA settings in Linux, the
card should work.
If your card is both SB and MSS compatible, I recommend using the MSS mode.
Most cards of this kind are not able to work in the SB and the MSS mode
simultaneously. Using the MSS mode provides 16 bit recording and playback.
ProAudioSpectrum 16 and compatibles
-----------------------------------
There are nothing special with these cards. Just don't enable any
other cards in case you don't have them also. The PAS16 has
a SB mode so the driver config program will prompt for the SB settings
do. Use I/O 0x220 and DMA1 for the SB mode. Ensure that you assign different
IRQ numbers for the SB and PAS16 modes.
With PAS16 you can use two audio device files at the same time. /dev/dsp (and
/dev/audio) is connected to the 8/16 bit native codec and the /dev/dsp1 (and
/dev/audio1) is connected to the SB emulation (8 bit mono only).
Gravis Ultrasound
-----------------
There are many different revisions of the Ultrasound card (GUS). The
earliest ones (pre 3.7) don't have a hardware mixer. With these cards
the driver uses a software emulation for synth and pcm playbacks. It's
also possible to switch some of the inputs (line in, mic) off by setting
mixer volume of the channel level below 10%. For recording you have
to select the channel as a recording source and to use volume above 10%.
GUS 3.7 has a hardware mixer.
GUS MAX and the 16 bit sampling daughtercard have a CS4231 codec chip which
also contains a mixer.
Configuring GUS is simple. Just enable the GUS support and GUS MAX or
the 16 bit daughtercard if you have them. Note that enabling the daughter
card disables GUS MAX driver.
With just the standard GUS enabled the configuration program prompts
for the I/O, IRQ and DMA numbers for the card. Use the same values than
with DOS.
With the daughter card option enabled you will be prompted for the I/O,
IRQ and DMA numbers for the daughter card. You have to use different I/O
and DMA values than for the standard GUS. The daughter card permits
simultaneous recording and playback. Use /dev/dsp (the daughtercard) for
recording and /dev/dsp1 (GUS GF1) for playback.
GUS MAX uses the same I/O address and IRQ settings than the original GUS
(GUS MAX = GUS + a CS4231 codec). In addition an extra DMA channel may be used.
Using two DMA channels permits simultaneous playback using two devices
(dev/dsp0 and /dev/dsp1). The second DMA channel is required for
full duplex audio.
To enable the second DMA channels, give a valid DMA channel when the config
program asks for the GUS MAX DMA (entering -1 disables the second DMA).
Using 16 bit DMA channels (5,6 or 7) is recommended.
If you have problems in recording with GUS MAX, you could try to use
just one 8 bit DMA channel. Recording will not work with one DMA
channel if it's a 16 bit one.
MPU401 and Windows Sound System
-------------------------------
Again. Don't enable these options in case your card is listed
somewhere else in this file.
Configuring these cards is obvious (or it should be). With MSS
you should propably enable the OPL3 synth also since
most MSS compatible cards have it. However check that this is true
before enabling OPL3.
VoxWare supports more than one MPU401 compatible cards at the same time
but the config program asks config info for just the first of them.
Adding the second or third MPU interfaces must be done manually by
editing sound/local.h (after running the config program). Add defines for
MPU2_BASE & MPU2_IRQ (and MPU3_BASE & MPU3_IRQ) to the file.
CAUTION!
The default I/O base of Adaptec AHA-1542 SCSI controller is 0x330 which
is also the default of the MPU401 driver. Don't configure the sound driver to
use 0x330 as the MPU401 base if you have a AHA1542. The kernel will not boot
if you make this mistake.
PSS
---
Even the PSS cards are compatible with SB, MSS and MPU401, you must not
enable these options when configuring the driver. The configuration
program handles these options itself. (You may use the SB, MPU and MSS options
together with PSS if you have another card on the system).
The PSS driver enables MSS and MPU401 modes of the card. SB is not enabled
since it doesn't work concurrently with MSS. The driver loads also a
DSP algorithm which is used to for the general MIDI emulation. The
algorithm file (.ld) is read by the config program and written to a
file included when the pss.c is compiled. For this reason the config
program asks if you want to download the file. Use the genmidi.ld file
distributed with the DOS/Windows drivers of the card (don't use the mt32.ld).
With some cards the file is called 'synth.ld'. You must have access to
the file when configuring the driver. The easiest way is to mount the DOS
partition containing the file with Linux.
It's possible to load your own DSP algorithms and run them with the card.
Look at the directory sound/pss_test for more info (in the VoxWare-3.0.tar.gz)
package.
AudioTriX Pro
-------------
You have to enable the OPL3 and SB (not SB Pro or SB16) drivers in addition
to the native AudioTriX driver. Don't enable MSS or MPU drivers.
Configuring ATP is little bit tricky since it uses so many I/O, IRQ and
DMA numbers. Using the same values than with DOS/Win is a good idea. Don't
attemp to use the same IRQ or DMA channels twice.
The SB mode of ATP is implemented so the the ATP driver just enables SB
in the proper address. The SB driver handles the rest. Yoy have to configure
both the SB driver and the SB mode of ATP to use the same IRQ, DMA and I/O
settings.
Also the ATP has a microcontroller for the General MIDI emulation (OPL4).
For this reason the driver asks for the name of a file containing the
microcode (TRXPRO.HEX). This file is usually located in the directory
where the DOS drivers were installed. You must have access to this file
when configuring the driver.
If you have the effects daughtercard, it must be initialized by running
the setfx program of snd-util-3.0.tar.gz package. This step is not required
when using the (future) binary distribution version of the driver.
Ensoniq SoundScape
------------------
The SoundScape driver handles initialization of MSS and MPU supports
itself so you don't need to enable other drivers than SoundScape
(enable also the /dev/dsp, /dev/sequencer and MIDI supports).
SoundScape driver uses the MSS compatible codec of the card. It's important
to note that /dev/dsp0 (/dev/dsp is linked to /dev/dsp0 by default)
doesn't work with SoundScape (yet). The 'ssinit' program needs /dev/dsp0 so
that's the reason why it's there. It's possible that 'primary' pcm channel
becomes supported later. Currently the card's firmware doesn't contain
support for it.
With 3.0 of VoxWare you have to change your system to use /dev/dsp1 by default
so execute: cd /dev;rm dsp;ln -s dsp1 dsp after you have installed VoxWare
3.0 (first time).
The configuration program asks two DMA channels and two interrupts. One IRQ
and one DMA is used by the MSS codec. The second IRQ is required for the
MPU401 mode (you have to use different IRQs for both purposes).
The second DMA channel is required for initialization of the microcontroller.
You have to use separate DMA channels.
The SoundScape card has a Motorola microcontroller which must initialized
_after_ boot (the driver doesn't initialize it during boot).
The initialization is done by running the 'ssinit' program which is
distributed in the snd-util-3.0.tar.gz package. You have to edit two
defines in the ssinit.c and then compile the program. You may run ssinit
manually (after each boot) or add it to /etc/rc.d/rc.local.
The ssinit program needs the microcode file that comes with the DOS/Windows
driver of the card. You will need to use version 1.30.00 or later
of the microcode file (sndscape.co0 or sndscape.co1 depending on
your card model). THE OLD sndscape.cod WILL NOT WORK. IT WILL HANG YOUR
MACHINE. The only way to get the new microcode file is to download
and install the DOS/Windows driver from ftp://ftp.ensoniq.com/pub.
Then you have to select the proper microcode file to use: soundscape.co0
is the right one for most cards and sndscape.co1 is for few (older) cards
made by Reveal and/or Spea. The driver has capability to detect the card
version during boot. Look at the boot log messages in /var/adm/messages
and locate the sound driver initialization message for the SoundScape
card. If the driver displays string <Ensoniq Soundscape (old)>, you have
an old card and you will need to use sndscape.co1. For other cards use
soundscape.co0.
Check /var/adm/messages after running ssinit. The driver prints
the board version after downloading the microcode file. That version
number must match the number in the name of the microcode file (extension).
Running ssinit with a wrong version of the sndscape.co? file is not
dangerous as long as you don't try to use a file called sndscape.cod.
If you have initialized the card using a wrong microcode file (sounds
are terrible), just modify ssinit.c to use another microcode file and try
again. It's possible to use an earlier version of sndscape.co[01] but it
may sound wierd.
Btw, The driver may complain something about "sscapeintr()" after
running ssinit. You should just ignore these messages.
MAD16 (Pro) and Mozart
----------------------
You need to enable just the MAD16 /Mozart support when configuring
the driver. _Don't_ enable SB, MPU401 or MSS. However you will need the
/dev/audio, /dev/sequencer and MIDI supports.
Mozart and OPTi 82C928 (the original MAD16) chips don't support
MPU401 mode so enter just 0 when the configuration program asks the
MPU/MIDI I/O base. The MAD16 Pro (OPTi 82C929) has MPU401 mode.
TB Tropez is based on the 82C929 chip. It has two MIDI ports.
The one connected to the MAD16 chip is the second one (there is a second
MIDI connector/pins somewhere??). If you have not connected the second MIDI
port, just disable the MIDI port of MAD16. The 'Maui' compatible synth of
Tropez is jumper configurable and not connected to the MAD16 chip.
It can be used by enabling the stand alone MPU401 support but you have
to initialize it by using the MS-DOS SNDSETUP program.
There are some other OPTi chips which may be used in soundcards such as
82C930 and MAC32. These chips are not supported by VoxWare yet. Please
contact me if you have a soundcard which uses these chips.
Some MAD16 based cards may cause feedback, whistle or terrible noise if the
line3 mixer channel is turned too high.
If you have a MAD16 card which have an OPL4 (FM + Wave table) synthesizer
chip (_not_ an OPL3), you have to apped line containing #define MAD16_OPL4
to the file linux/dirvers/sound/local.h (after running make config).
MV Jazz (ProSonic)
------------------
The Jazz16 driver is just a hack made to the SB Pro driver. However it works
fairly well. You have to enable SB, SB Pro (_not_ SB16) and MPU401 supports
when configuring the driver. The configuration program asks later if you
want support for MV Jazz16 based cards (after asking SB base address). Answer
'y' here and the driver asks the second (16 bit) DMA channel.
The Jazz16 driver uses the MPU401 driver in a way which will cause
problems if you have another MPU401 compatible card. In this case you must
give address of the Jazz16 based MPU401 interface when the config
program prompts for the MPU401 information. Then look at the MPU401
spesific section for instructions about configuring more than one MPU401 cards.
Logitech Soundman Wave
----------------------
Read the above MV Jazz spesific instructions first.
The Logitech SoundMan Wave (don't confuse with the SM16 or SM Games) is
a MV Jazz based card which has an additional OPL4 based wave table
synthesizer. The OPL4 chip is handled by an on board microcontroller
which must be initialized during boot. The config program asks if
you have a SM Wave immediately after asking the second DMA channel of jazz16.
If you answer 'y', the config program will ask name of the file containing
code to be loaded to the microcontroller. The file is usually called
MIDI0001.BIN and it's located in the DOS/Windows driver directory. The file
may also be called as TSUNAMI.BIN or something else (older cards?).
The OPL4 synth will be inaccessible without loading the microcontroller code.
Also remember to enable MPU401 support if you want to use the OPL4 mode.
NOTE! Don't answer 'y' when the driver asks about SM Games support
(the next question after the MIDI0001.BIN name). However
aneswering 'y' is not dangerous.
Sound Galaxies
--------------
There are many different Sound Galaxy cards made by Aztech. The 8 bit
ones are fully SB or SB Pro compatible and there should be no problems
with them.
The older 16 bit cards (SG Pro16, SG NX Pro16, Nova and Lyra) have
an EEPROM chip for storing the configuration data. There is a microcontroller
which initializes the card to match the EEPROM settigs when the machine
is powered on. These cards actually behave just like they have jumpers
for all of the settings. Configure VoxWare for MSS, MPU, SB/SB Pro and OPL3
supports with these cards.
The config program asks if you want support for the mixer of
SG NX Pro. Answer 'y' to these questions if you have one of the above 8 or
16 bit Aztech cards.
There are some new Sound Galaxies in the market. I have no experience with
them so read the card's manual carefully.
Reveal cards
------------
There are several different cards made/marketed by Reveal. Some of them
are compatible with SoundScape and some use the MAD16 chip. You may have
to look at the card and try to identify origin of the card.
Diamond
-------
The oldest (Sierra Aria based) soundcards made by Diamond are not supported
(they may work if the card is initialized using DOS). The recent (LX?)
models are based on the MAD16 chip which is supported by VoxWare.
Audio Excel DSP16
-----------------
See comments in aedsp16.c.
PCMCIA cards
------------
Sorry, can't help. Some cards may work and some don't.
TI TM4000M notebooks
--------------------
These computers have a built in sound support based on the Jazz chipset.
Look at the instructions for MV Jazz (above). It's also important to note
that there is something wrong with the mouse port and sound at least on
some TM models. Don't enable the "C&T 82C710 mouse port support" when
configuring Linux. Having it enabled is likely to cause mysterious problems
and kernel failures when sound is used.
Others?
-------
Since there are so many different soundcards, it's likely that I have
forgotten to mention many of them. Please inform me if you know yet another
card which works with Linux, please inform me (or is anybody else
willing to maintain a database of supported cards (just like in XF86)?).
Cards not supported yet
=======================
First of all. There is an easy way to make most soundcards to work
with Linux. Just use the DOS based driver to initialize the card
to a _known_ state. Then ctrl-alt-del to Linux. If Linux is configured
to use the sama I/O, IRQ and DMA numbers than DOS, the card could work.
Don't get fooled with SB compatibility. Most cards are compatible with
SB but that may require a TSR which is not possible with Linux. If
the card is compatible with MSS, it's a better choise. Some cards
don't work in the SB and MSS modes at the same time.
There are some cards which will be supported by VoxWare sooner or later
(currently at least cards based on the ESS chipset). Such cards are
so common that there is some idea in writing the driver. Check the
VoxWare home page (http://personal.eunet.fi/pp/voxware) for latest
information.
Then there are cards which are no longer manufactured and/or which
are relatively rarely used (such as the 8 bit ProAudioSpectrum
models). It's extremely unlikely that such cards never get supported.
Adding support for a new card requires much work and increases time
required in maintaining the driver (some changes need to be done
to all low level drivers and be tested too, maybe with multiple
operating systems). For this reason I have made a desicion to not support
obsolete cards. It's possible that someone else makes a separately
distributed driver (diffs) for the card. Version v4.0 will be much more
modular so making separately distributed drivers will be easier with it.
(The bad news is that v4.0 will not be available before late -96).
Writing a driver for a new card is not possible if there are no
programming information available about the card. If you don't
find your new card from this file, look from the home page
(http://personal.eunet.fi/pp/voxware). Then please contact
manufacturer of the card and ask if they have (or are willing to)
released technical details of the card. Do this before contacting me. I
can only answer 'no' if there are no programming information available.
Some companies don't give low level technical information about their
products to public or at least their require signing a NDA.
I have also made decicion to not accept code based on reverse engineering
to VoxWare. There are three main reasons: First I don't want to break
relationships to sound card manufacturers. The second reason is that
maintaining and supporting a driver withoun any specs will be a pain. The
third reason is that why shoud we help such companies in selling their
products to Linux users when they don't want to sell to Linux users
at all?
Unfortunately many of the leading soundcard manufacturers are not willing
to co-operate with Linux/Unix community. For example: Creative Technology
doesn't give information about the ASP chip and the Emu synth chip of AWE32
and SB32. Turtle Beach don't give information about any of their
products. MediaVision requires NDA before they are willing to
give information about the Jazz16 chip (fortunately Logitech gave
the info about SM Wave).
So at least the above three companies are out until they are willing to
release documentation about their products (the situation is the
same with many DOS based freeware/shareware games and utilities). If
you want to use Linux/Unix with their cards, please don't try to push
me. It's a better idea to contact the manufacturer and explain that
you want to use your card with Linux/Unix. You could also try to sell
your card to somebody else and then buy a card that is supported by VoxWare.
However it's possible that things change and a driver gets written
for some of the banned cards. Please, don't send me messages asking if
there is any plans to write a driver for the cards mentioned above. I
will put any news to the VoxWare www home page (see below).
There are some common audio chipsets that are supported yet. For example
the ESS chips and Sierra Aria. It's likely that these architectures
get some support in future but I can't make any promises. Just look
at the home page for latest info.
Information about unsupported soundcards and chipsets is welcome as well
as free copies of soundcards, SDKs and operating systems.
If you have any corrections and/or comments, please contact me.

Building a loadable sound driver
================================
Loadable module support in version 3.5 of VoxWare is mostly rewritten since
the previous version (3.0.1). This means that some things have changed.
To compile the sound driver as a loadable module you have to perform
the following steps:
1) Install modules-1.2.8.tar.gz package (or later if available).
2a) Check that symbol remap_page_range is defined in linux/init/ksyms.c.
Insert a line containing "X(remap_page_range)," if required. The driver will
not load if this line is missing.
2b) Recompile kernel with soundcard support disabled.
3) Boot the new kernel.
4) cd to the sound driver source directory (this directory). It's no
longer required that the sound driver sources are installed in the
kernel source tree (linux/drivers/sound). When installing a separately
distributed sound driver you may install the sources for example to
/usr/src/sound.
5) Execute make in the sound driver source directory. Enter
configuration parameters as described in Readme.cards. Then just wait until
the driver is compiled OK.
6) Copy sound.o to the directory where insmod expects to find it.
("make install" copies it to /lib/modules/misc).
7) Use command "insmod sound" to load the driver.
8) The sound driver can be removed using command "rmmod sound".
Parameters accepted by the loadable sound driver
================================================
Setting DMA buffer size
-----------------------
The driver allocates a DMA buffer (or two for full duplex devices)
every time the audio device (/dev/dsp or /dev/audio) is opened
and frees it when the device is closed. Size of this buffer is defined
when the driver is configured (the last question). The buffer size
can be redefined when loading the driver if required (note that this is
an optional feature which is not normally required). The buffer size
is redefined by adding dma_pagesize= parameter to the insmod command line.
For example:
insmod sound dma_buffsize=32768
Minimum buffer size is 4096 and the maximum depends on the DMA channe.
For 8 bit channels (0 to 3) the limit is 64k and for 16 bit ones (5 to 7)
it's 128k. Driver selects a suitable buffer size automaticly in case
you try to spesify an invalid size.
Q: What is the right DMA buffer size?
A: It depends on the sampling rate, machine speed and the load of the system.
Large buffers are required on slow machines, when recording/playing CD-quality
audio or when there are other processes running on the same system. Also
recording to hard disk is likely to require large buffers.
Very small buffers are sufficient when you are just playing 8kHz audio files
on an empty P133 system. Using a 128k byffer just wastes 120k (or 250k)
of valuable physical RAM memory.
The right buffer sice can be easily found by making some experiments
with the dma_buffsize= parameter. I use usually 16k buffers on a DX4/100 system
and 64k on an old 386 system.
NOTE! DMA buffers are used only by /dev/audio# and /dev/dsp# devices.
Other device files don't use them but there are two exceptions:
GUS driver uses DMA buffers when loading samples to the card.
Ensoniq SoundScape driver uses them when doanloading the microcode
file (sndscape.co[012]) to the card. Using large buffers doesn't
increase performance in these cases.
Configuring device parameters when loading the driver
-----------------------------------------------------
The loadable version of the sound driver accepts now the same
sound= parameter that has been available in the LILO command line.
In this way it's possible to change I/O port, IRQ and DMA addresses
and to enable/disable various cards at load time. Normally
the driver uses the configuration parameters entered when compiling
and configuring the driver.
Look at Readme.linux for more info.
NOTE! This method is not normally required. You should use it only when
you have to use different configuration than normally. The sound=
command line parameter is error phrone and not recommended.
Debugging and tracing
---------------------
Modularized sound driver doesn't display messages during initialization as
the kernel compiled one does. This feature can be turned on by adding
init_trace=1 to the insmod command line.
For example:
insmod sound init_trace=1

VoxWare v3.0
------------
All features of v2.90-2 should work as earlier. There could be some
omissions but they are unintentional. I started this version thread
after v2.3 so all features implemented before it are there.
New features
============
There are now two new device interfaces. The /dev/midi## is a raw
tty like interface to MIDI ports. There is a device file for each MIDI
port on your system. They are named (/dev/midi00 to /dev/midiNN).
The second addition is the /dev/music which is higher level interface
than the old /dev/sequencer. It's intended for writing device independent
applications like sequencers.
/dev/midi##
-----------
This interface should be usefull for applications like MIDI sysex librarians.
There are (currently) no timing features so making music could be impossible.
There are as many /dev/midi## devices as there are MIDI ports in the system.
The /dev/midi00 is connected to the first one, /dev/midi01 to the second etc.
These devices work like tty devices in raw mode. Everything written to them is
sent out to the MIDI port. There is currently an extra delay of at most
1/100th of sec but it will be removed later.
The reading algorithm is little bit more complicated. There are two different
cases:
1) There is at least one byte in the input buffer.
The read returns as many bytes as it can without waiting for more bytes.
For example when a process reads 100 bytes and there are 10 bytes in the
buffer, the read returns just 10 bytes.
2) The input buffer is empty when the process calls read.
The read waits for the first byte and then continues as in case 1. By
default it waits infinitely but there is an ioctl for setting a timeout
for this. The ioctl(fd, SNDCTL_MIDI_PRETIME, &time) changes the timeout.
The time is given in 1/10th of seconds (10 means one second).
Other ioctl calls:
ioctl(fd, SNDCTL_MIDI_MPUMODE, &mode) is available for full MPU-401
compatible devices such as MPU-IPC-T, MQ PC Midi Card or MQX-32.
It's not available for the so called MPU UART ports of some soundcards
(PAS16, SB16 etc). By default the MIDI port is in UART mode after open.
If this ioctl is called with mode=1, the interface is put to the intelligent
(coprocessor) mode. NOTE! The MIDI port will be reset when this ioctl is called.
It could have some strange effects if not called immediately after open. This
vall returns EINVAL if the midi port doesn't support the MPU-401 intelligent
mode.
ioctl(fd, SNDCTL_MIDI_MPUCMD, &cmdstruct) is valid only if the MIDI port
is put to the coprocessor mode using ioctl(SNDCTL_MIDI_MPUMODE). It's used to
send commands to a MPU-401 compatible MIDI cards. Please refer to the
MPU-401 Technical Reference Manual (or Music Quest Technical Reference
Manual) for descriptions of the commands.
The argument of SNDCTL_MIDI_MPUCOMMAND is of type mpu_command_rec. It
has the following fields:
typedef struct {
unsigned char cmd;
char nr_args, nr_returns;
unsigned char data[30];
} mpu_command_rec;
where:
cmd Contains the command number.
nr_args Number of arguments of the command.
MUST BE INITIALIZED BEFORE CALL
nr_returns Number of bytes returned by the command.
MUST BE INITIALIZED BEFORE CALL
data Buffer for the command arguments and returned
data.
Be extremely carefull with the nr_args and nr_returns fields. They
must match the command. An incorrect value will put the card and
the driver out of sync. Refer to the MPU-401/MQX-32M documentation for further
datails.
/dev/music (/dev/sequencer2)
----------------------------
This device file works much like the /dev/sequencer which has been present
since the beginning. The main differences are the following:
- /dev/sequencer makes the MIDI ports to look like the synth devices. In fact
the result is somewhere between the MIDI specification and the synth devices of
/dev/sequencer. Both kind of devices are accessed using the SEQ_START_NOTE()
like macros. The voice number parameters of the API macros have been redefined
to denote MIDI channels. This means that the driver allocates voices for
the channels automaticly (this is a responsibility/right of an application
with /dev/sequencer). The result is that a SEQ_START_NOTE() macro has
similar effects for a synth channel than on a MIDI port. This kind of
solution provides better device independence than the /dev/sequencer. The
drawback is that the new interface doesn't permit so low level access to the
device as the /dev/sequencer does. An application developer must choose between
these two interfaces. I think the old /dev/sequencer is better for applications
like module players while the new one is better for making generic sequencer
programs.
- There are no separate MIDI devices with the /dev/sequencer2. The
ioctl(SNDCTL_SEQ_NRMIDIS) returns always zero. Instead the MIDI ports are
shown as synth devices. ioctl(SNDCTL_SEQ_NRSYNTHS) on /dev/sequencer2 will
return sum of internal synthesizers (GUS, OPL3) and MIDI ports in the systems.
- The new interface is used much like the ordinary /dev/sequencer. The
event format is new so you have to use the API macros defined in the
sys/soundcard.h. The interface is will propably change before the final 3.0
release but using the API macros should ensure compatibility in source level.
The new event format is not recognized by version 2.X so don't try to
distribute binaries compiled with soundcard.h of v3.X.
- The basic API useage is similar to the current one. There are some new
macros but the older ones should work as earlier. The most important
incompatibility is that the /dev/sequencer2 driver allocates voices itself.
The other one is that the application must send SEQ_START_TIMER() as its
first event. Otherwise the timer is not started and the application waits
infinitely.
There are several new features but I don't document them here. There are
some info in the soundcard.h (near the end). I have also included some
sample code in the directory v30. Full documentation will
appear in the Hacker's Guide later.
Don't hesitate to contact me in case you have questions or comments.

*
* The low level driver for Crystal CS4232 based cards. The CS4232 is a PnP
* compatible chip which contains a CS4231A codec, SB emulation, a MPU401
* compatible MIDI port, joystick and synthesizer and IDE CD-ROM interfaces.
* This is just a temporary driver until full PnP support gets inplemented.
* Just the WSS codec, FM synth and the MIDI ports are supported. Other

/*
* sound/mad16.c
*
* Initialization code for OPTi MAD16 compatible audio chips. Including
*
* OPTi 82C928 MAD16 (replaced by C929) OAK OTI-601D Mozart
* OPTi 82C929 MAD16 Pro
*
* These audio interface chips don't prduce sound themselves. They just connect
* some other components (OPL-[234] and a WSS compatible codec) to the PC bus
* and perform I/O, DMA and IRQ address decoding. There is also a UART for
* the MPU-401 mode (not 82C928/Mozart). The Mozart chip appears to be
* compatible with the 82C928 (can anybody confirm this?).
*
* NOTE! If you want to set CD-ROM address and/or joystick enable, define
* MAD16_CONF in local.h as combination of the following bits:
*
* 0x01 - joystick disabled
*
* CD-ROM type selection (select just one): 0x00 - none 0x02 - Sony 31A
* 0x04 - Mitsumi 0x06 - Panasonic (type "LaserMate", not
* "SoundBlaster") 0x08 - Secondary IDE (address 0x170) 0x0a - Primary
* IDE (address 0x1F0)
*
* For example Mitsumi with joystick disabled = 0x04|0x01 = 0x05 For example
* LaserMate (for use with sbpcd) plus joystick = 0x06
*
* MAD16_CDSEL: This defaults to CD I/O 0x340, no IRQ and DMA3 (DMA5 with
* Mitsumi or IDE). If you like to change these, define MAD16_CDSEL with the
* following bits:
*
* CD-ROM port: 0x00=340, 0x40=330, 0x80=360 or 0xc0=320 OPL4 select: 0x20=OPL4,
* 0x00=OPL3 CD-ROM irq: 0x00=disabled, 0x04=IRQ5, 0x08=IRQ7, 0x0a=IRQ3,
* 0x10=IRQ9, 0x14=IRQ10 and 0x18=IRQ11.
*
* CD-ROM DMA (Sony or Panasonic): 0x00=DMA3, 0x01=DMA2, 0x02=DMA1 or
* 0x03=disabled or CD-ROM DMA (Mitsumi or IDE): 0x00=DMA5, 0x01=DMA6,
* 0x02=DMA7 or 0x03=disabled
*
* For use with sbpcd, address 0x340, set MAD16_CDSEL to 0x03 or 0x23.

$Id: sound.doc,v 1.8 1997/02/22 09:38:15 peter Exp $
Instructions on using audio on a FreeBSD 2.1 (or 2.0-current) system.
See also /sys/i386/conf/LINT.
To enable sound driver support, the controller sound code must be included
in your config file:
# SB = SoundBlaster; PAS = ProAudioSpectrum; GUS = Gravis UltraSound
# Controls all sound devices
controller snd0
Uncomment one or more of these device entries, depending on what type of
sound card you have:
# ProAudioSpectrum PCM and Midi - for PAS
#device pas0 at isa? port 0x388 irq 10 drq 6
# SoundBlaster DSP driver - for SB, SB Pro, SB16, PAS(emulating SB)
#device sb0 at isa? port 0x220 irq 7 drq 1
# SoundBlaster 16 DSP driver - for SB16 - requires sb0 device
#device sbxvi0 at isa? drq 5
# SoundBlaster 16 MIDI - for SB16 - requires sb0 device
#device sbmidi0 at isa? port 0x300
# Gravis UltraSound - for GUS, GUS16, GUSMAX
# For cards that use 2 DMA Channels:
# drq = Write DMA Channel, flags = Read DMA Channel
#device gus0 at isa? port 0x220 irq 11 drq 1 flags 0x3
# Gravis UltraSound 16 bit option - for GUS16 - requires gus0
#device gusxvi0 at isa? port 0x530 irq 7 drq 3
# MS Sound System (AD1848 Based Boards)
#device mss0 at isa? port 0x530 irq 10 drq 1
# Yamaha OPL-2/OPL-3 FM - for SB, SB Pro, SB16, PAS
#device opl0 at isa? port 0x388
# MPU-401 - for MPU-401 standalone card
#device mpu0 at isa? port 0x330 irq 6 drq 0
# 6850 UART Midi
#device uart0 at isa? port 0x330 irq 5
You may add one or more of the following depending on what you do and don't
want compiled into your kernel. Note: Excluding things with EXCLUDE_...
is NOT recommended unless you really know what you're doing.
#options EXCLUDE_AUDIO # NO digital audio support
#options EXCLUDE_SEQUENCER # NO sequencer support
#options EXCLUDE_MIDI # NO MIDI support whatsoever
#options EXCLUDE_SBPRO # EXCLUDE SB Pro support
#options EXCLUDE_SB_EMULATION # NO PAS SB emulation support
#options EXCLUDE_GUS_IODETECT # NO GUS io detection
#options EXCLUDE_PRO_MIDI # NO PAS MIDI support
Other Options:
#options SYMPHONY_PAS
Adds some code to make pas work with Symphony chipsets. Only use
this if your pas doesn't work and you have a Symphony chipset.
#options BROKEN_BUS_CLOCK
Some systems with the OPTI chipset and a PAS will require you to
use this option. Symptoms are that you will hear a lot of clicking and
popping sounds, like a geiger counter, coming out of the PAS even when
it is not playing anything.
#options MOZART_PORT
Adds support for Mozart (OAK OTI-601). (Part of the MSS driver)
#options OPTI_MAD16_PORT
Adds support for the OPTI MAD16 Chip. (Part of the MSS driver)
If your soundcard has a chip labeled "OPTi 82C929" then try this.
#options __SGNXPRO__
Adds support for the SG NX Pro mixer. (Part of the SB driver)
#options JAZZ16
Adds support for the MV Jazz16 (ProSonic etc). (Part of the SB Driver)
#options SM_WAVE
Adds support for the SoundMan Wave (Part of the SB Driver)
Note: You will need to do some work to get this to work.
See i386/isa/sound/configure.c
#options SM_GAMES
Adds support for the Logitech SoundMan Games (Part of the SB Driver)
#options PAS_JOYSTICK_ENABLE
Enables the gameport on the ProAudio Spectrum
NOTE: The MPU-401 driver may or may not work, and is unfortunately
unverifiable since no one I know has one. If you can test this,
please let me know! Also note that you will have to change these
settings if your soundcard is set for a non-standard address or IRQ.
Please check your documentation (or verify with any provided DOS utilities
that may have come with your card) and set the IRQ or address fields
accordingly.
Also: You can configure more then one card on a single DMA using
the conflicts keyword in your configuration file. This is useful for boards
with more then one type of emulation.
Probing problems: Since the SB16 uses the same IRQ and addresses for
the different drivers, some of the snd drivers will not be probed because
the kernel thinks there is a conflict. This can be worked-around by
using the "conflicts" keyword on the sb16's device line.
