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:

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.
