|
|
.Os
|
|
.Sh NAME
|
|
.Nm snd_es137x
|
|
.Nd "Ensoniq AudioPCI ES137x bridge device driver"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel, place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device sound"
|
|
.Cd "device snd_es137x"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a module at boot time, place the
|
|
following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
snd_es137x_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
bridge driver allows the generic audio driver
|
|
.Xr sound 4
|
|
to attach to the Ensoniq 137x audio cards.
|
|
.Ss Runtime Configuration
|
|
The following
|
|
.Xr sysctl 8
|
|
variables are available in addition to those available to all
|
|
.Xr sound 4
|
|
devices:
|
|
.Bl -tag -width ".Va hw.snd.pcm%d.latency_timer" -offset indent
|
|
.It Va hw.snd.pcm%d.latency_timer
|
|
Controls the PCI latency timer setting.
|
|
Increasing this value will solve most popping and crackling issues
|
|
(especially on VIA motherboards).
|
|
.It Va hw.snd.pcm%d.spdif_enabled
|
|
Enables S/PDIF output on the primary playback channel.
|
|
This
|
|
.Xr sysctl 8
|
|
variable is available only if the device is known to support S/PDIF output.
|
|
.It Va dev.pcm.%d.polling
|
|
Experimental polling mode, where the driver operates by querying the device
|
|
state on each tick using
|
|
.Xr callout 9 .
|
|
Polling is disabled by default.
|
|
Do not enable it unless you are facing weird interrupt problems or if the
|
|
device cannot generate interrupts at all.
|
|
.El
|
|
.Sh HARDWARE
|
|
The
|
|
.Nm
|
|
driver supports the following sound cards:
