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  dev-
            ice  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. 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.
