mixerctl(1) User Commands mixerctl(1)NAMEmixerctl - 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.
