audiocfg

AUDIOCFG(1)						    BSD General Commands Manual 					       AUDIOCFG(1)

NAME

     audiocfg -- configure default audio device

SYNOPSIS

     audiocfg list
     audiocfg default index
     audiocfg test index

DESCRIPTION

     The audiocfg utility helps maintaining the audio and mixer device symlinks.

     Run with ``list'', it lists the available audio devices and shows the currently selected default audio device.  Called with ``test'', it
     plays a tone of 2 seconds for each channel of the device with the index index.  Called with ``default'', it sets the default audio device to
     the one with the index index.

     audiocfg needs access to /dev/drvctl and write access to /dev (when used with ``default'') to work.

FILES

     /dev/audio  Symlink to default audio device.

     /dev/audio[0-9]*
		 Available audio devices.

     /dev/audioctl
		 Symlink to default audio control device.

     /dev/audioctl[0-9]*
		 Available audio control devices.

     /dev/drvctl
		 Used for finding the corresponding audio driver to an audio device.

     /dev/mixer  Symlink to default mixer device.

		 Available mixer devices.

     /dev/sound  Symlink to default audio device (for the difference to /dev/audio, see audio(4)).
