mixerctl(1) User Commands mixerctl(1)NAME
mixerctl - audio mixer control command line application
SYNOPSIS
/usr/sbin/mixerctl [-a | -d dev] [-iv] [-e | -o]
DESCRIPTION
Some audio devices support the audio mixer functionality. See mixer(7I) for a complete description of the audio mixer. The mixerctl command
is used to control the mode of the audio mixer and to get information about the audio mixer and the audio device. See audio(7I) for
details.
OPTIONS
The following options are supported. If none are specified, option -i is assumed:
-a The command applies to all audio devices.
-d dev The dev argument specifies an alternate audio control device for the command to use.
-e Enables the audio mixer function if the audio device supports it. If supported, the audio mixer may be enabled at any time. The
command silently ignores the enable option if the audio mixer is already enabled.
-i Prints the audio device type information for the device and indicates whether the audio device uses the audio mixer. If the
device does use the audio mixer, this option displays the audio mixer's mode.
-o Turns off the audio mixer function if the audio device supports it. If supported, the audio mixer may be turned off if only one
process has the device opened with the O_RDWR flag, or, if two different processes have the device opened, one with the O_RDONLY
flag and the other with the O_WRONLY flag. (See open(2).) The command silently ignores the disable option if the audio mixer
function is already disabled.
-v Verbose mode. Prints the audio_info_t structure for the device, along with the device type information. This option implies the
-i option.
ENVIRONMENT VARIABLES
AUDIODEV If the -d and -a options are not specified, the AUDIODEV environment variable is consulted. If set, AUDIODEV will contain the
full path name of the user's default audio device. The default audio device will be converted into a control device, and then
used. If the AUDIODEV variable is not set, /dev/audioctl is used.
FILES
/dev/audioctl
/dev/sound/{0...n}ctl
