       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.

       ctrl# value
	      Change value of a	mixer control.

       <no arg>
	      Display current/possible settings.

       ossmix without any arguments displays the current settings of  the  de-
       fault  mixer device (usually the	motherboard sound chip). This printout
       can also	be used	to find	out the	supported control names	and their pos-
       sible  values.  Currently  all  controls	accept an ON/OFF value,	a mono
       value (0	to 100)	or a stereo value (left:right where both channel  vol-
       umes  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 con-
       trol 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:
	       vol <both/leftvol>[:<rightvol>] (currently 50:50)
	       pcm <both/leftvol>[:<rightvol>] (currently 50:50)
	       speaker <monovol> (currently 21)
	       line <both/leftvol>[:<rightvol>]	(currently 32:32)
	       line.rec	ON|OFF (currently OFF)
	       mic <monovol> (currently	16)
	       mic.rec ON|OFF (currently ON)
	       cd <both/leftvol>[:<rightvol>] (currently 100:100)
	       cd.rec ON|OFF (currently	OFF)
	       pcm2 <both/leftvol>[:<rightvol>]	(currently 75:75)
	       line1 <both/leftvol>[:<rightvol>] (currently 32:32)
	       line1.rec ON|OFF	(currently OFF)
	       line2 <monovol> (currently 32)
	       line2.rec ON|OFF	(currently OFF)
	       line3 <monovol> (currently 0)
	       line3.rec ON|OFF	(currently OFF)
	       mic.micboost ON|OFF (currently ON)
	       mic.micbias ON|OFF (currently ON)
	       mute.pcmmute ON|OFF (currently OFF)
	       mute.pcm2mute ON|OFF (currently OFF)
	       mute.micmute ON|OFF (currently OFF)
	       mute.cdmute ON|OFF (currently OFF)
	       mute.linemute ON|OFF (currently OFF)
	       mute.line1mute ON|OFF (currently	OFF)
	       mute.line2mute ON|OFF (currently	OFF)
	       mute.line3mute ON|OFF (currently	OFF)

       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 ac-
       cessed.	To find	the available mixer devices, type ossinfo -x and  look
       under the Mixers	heading	for available mixer devices.

       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 "os-
       smix pcm	50" the	both channel volumes will be set to 50.

       In addition to the old mixer there are now some (usually	 ON/OFF)  set-
       tings.	These  settings	 are  device  specific and don't work with all
       soundcards.  The	easiest	way to find them out is	to start ossmix	 with-
       out 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 vol-
	      ume  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.
