MIXER(8)

NAME
mixer - set/display soundcard mixer values

SYNOPSIS
mixer
mixer setting [lvalue:rvalue]
mixer +rec | -rec [device]

DESCRIPTION
The mixer command is used to set and display soundcard mixer settings. It may also be used to start and stop recording from the soundcard. The list of mixer settings that may be modified are:

vol, bass, treble, synth, pcm, speaker, mic, cd, mix, pcm2, rec, igain, ogain, line1, line2, and line3.

Not all mixer settings are available on all soundcards.

When mixer is run without any arguments, all settings that are supported by the soundcard will be displayed. If the setting argument is specified, then only the value for the setting mixer will be displayed.

To modify the mixer value setting, the optional left and right channel settings of lvalue:rvalue may be specified. The lvalue and rvalue arguments may be from 0 - 100.

To start recording, use the +rec argument. To stop recording, use the -rec argument. The optional argument device may be specified to use a different mixer device. The default device is /dev/mixer.
