NAME

       ossmix - Open Sound System command-line mixer program.

SYNOPSIS

       ossmix [-d <dev#>] [-achqD] [control name] [value]

DESCRIPTION

       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.

OPTIONS

       -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.

       -v[1|2]
              Verbose mode. -v2 prints more detailed infoamation than -v1.

       ctrl# value
              Change value of a mixer control.

       <no arg>
              Display current/possible settings.

USAGE

       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:

               Selected mixer 0/Creative AudioPCI
               Known controls are:

               mute.line3mute ON|OFF (currently OFF)

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.  For example:

               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".

EXAMPLES

       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
              Toggle micboost.

       ossmix mplayer +2
              Raise mplayer volume by 2. This would only work if mplayer is using the virtual mixer.
