ossmix - Open Sound System command-line mixer program.
ossmix [-d <dev#>] [-achqD] [control name] [value]
ossmix is a simple command-line mixer utility that is used to display
the mixer settings of physical and virtual audio devices. OSS version 4
has an extended mixer API which supports some device specific features
that may not available using other mixer applications.
-D Display device information.
-a Dump mixer settings for all mixers (normal format).
-c Dump mixer settings for all mixers (command format).
-h Display usage information.
-q Quiet mode.
Verbose mode. -v2 prints more detailed infoamation than -v1.
Change value of a mixer control.
Display current/possible settings.
ossmix without any arguments displays the current settings of the
default mixer device (usually the motherboard sound chip). This
printout can also be used to find out the supported control names and
their possible values. Currently all controls accept an ON/OFF value, a
mono value (0 to 100) or a stereo value (left:right where both channel
volumes can be between 0 and 100). The value can also be expressed in a
relative form (e.g. +1 to add 1 to the previous volume). An ON/OFF
control can also receive a TOGGLE value. If a control has a name in
quotes following the normal output, than the name can be used instead
of the control when setting a value.
The following is a sample printout produced by ossmix:

SELECTING MIXER DEVICE
It's possible to select the mixer device by using the -d<mixernumber>
command line argument. This argument (when used) should be the first
one on the command line. By default the mixer number 0 will be
accessed. To find the available mixer devices, type ossinfo -x and
look under the Mixers heading for available mixer devices.
CHANGING MIXER SETTINGS
Changing the values is done just like with the original "mixer" applet.
ossmix pcm 50:60
The above sets the pcm control (audio playback volume) so that the left
channel volume is 50 and the right channel volume is 60. With just
"ossmix pcm 50" the both channel volumes will be set to 50.
In addition to the old mixer there are now some (usually ON/OFF)
settings. These settings are device specific and don't work with all
soundcards. The easiest way to find them out is to start ossmix
without command line arguments (other than -d#).
Some control names contain a dot ("."). This dot is required when
changing the value. For example: "ossmix -d0 mic.micboost ON".
ossmix vol 50
Set the vol control volume to 50. If the pcm control is a stereo
control, than both channels will be set to 50.
ossmix vol 50:60
Set the vol control so that the left channel volume is 50 and
the right channel volume is 60.
ossmix vol +2
Raise vol volume by 2.
ossmix -- vol +2:-2
Raise the left channel volume by 2, and lower right channel
volume by 2. The "--" is needed on some systems so that the
"-2" won't be mistaken for a parameter.
ossmix micboost ON
Set micboost to ON.
ossmix micboost TOGGLE
ossmix mplayer +2
Raise mplayer volume by 2. This would only work if mplayer is
using the virtual mixer.
