.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is used to set and display soundcard mixer device levels.
|
|
It may
|
|
also be used to start and stop recording from the soundcard.
|
|
The list
|
|
of mixer devices that may be modified are:
|
|
.Pp
|
|
.Bd -ragged -offset indent
|
|
vol, bass, treble, synth, pcm, speaker, line, mic, cd, mix,
|
|
pcm2, rec, igain, ogain, line1, line2, and line3.
|
|
.Ed
|
|
.Pp
|
|
Not all mixer devices are available.
|
|
.Pp
|
|
Without any arguments,
|
|
.Nm
|
|
displays the current settings for all supported devices, followed by information
|
|
about the current recording input devices.
|
|
If the
|
|
.Ar dev
|
|
argument is specified,
|
|
.Nm
|
|
displays only the value for that
|
|
.Ar dev .
|
|
.Pp
|
|
To modify the mixer value
|
|
.Ar dev ,
|
|
the optional left and right channel settings of
|
|
.Ar lvol Ns Op : Ns Ar rvol
|
|
may be specified.
|
|
The
|
|
.Ar lvol
|
|
and
|
|
.Ar rvol
|
|
arguments may be from 0 - 100.
|
|
Omitting
|
|
.Ar dev
|
|
and including only the channel settings will change the main volume level.
|
|
.Pp
|
|
If the left or right channel settings are prefixed with
|
|
.Cm +
|
|
or
|
|
.Cm - ,
|
|
the value following will be used as a relative adjustment, modifying the
|
|
current settings by the amount specified.
|
|
.Pp
|
|
If the
|
|
.Fl s
|
|
flag is used, the current mixer values will be displayed in a format suitable
|
|
for use as the command-line arguments to a future invocation of
|
|
.Nm
|
|
(as above).
|
|
.Pp
|
|
The
|
|
.Fl S
|
|
flag provides the above output without mixing field separators.
|
|
.Pp
|
|
To change the recording device you use one of:
|
|
.Bl -tag -width =rec -offset indent
|
|
.It Cm ^rec
|
|
toggles
|
|
.Ar rdev
|
|
of possible recording devices
|
|
.It Cm +rec
|
|
adds
|
|
.Ar rdev
|
|
to possible recording devices
|
|
.It Cm -rec
|
|
removes
|
|
.Ar rdev
|
|
from possible recording devices
|
|
.It Cm =rec
|
|
sets the recording device to
|
|
.Ar rdev
|
|
.El
|
|
.Pp
|
|
The above commands work on an internal mask.
|
|
After all the options
|
|
have been parsed, it will set then read the mask from the sound card.
|
|
This will let you see EXACTLY what the soundcard is using for the
|
|
recording device(s).
|
|
.Pp
|
|
The option recsrc will display the current recording devices.
|
|
.Pp
|
|
The option
|
|
.Fl f
|
|
.Ar device
|
|
will open
|
|
.Ar device
|
|
as the mixer device.
