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.
