AUDIOCTL(1)		  BSD General Commands Manual		   AUDIOCTL(1)

NAME
     audioctl -- control audio device

SYNOPSIS
     audioctl [-d device] [-n] -a
     audioctl [-d device] [-n] name ...
     audioctl [-d device] [-n] -w name=value ...

DESCRIPTION
     The audioctl command displays or sets various audio system	driver vari-
     ables.  If	a list of variables is present on the command line, then
     audioctl prints the current value of those	variables for the specified
     device.  If the -a	flag is	specified, all variables for the device	are
     printed.  If the -w flag is specified audioctl attempts to	set the	speci-
     fied variables to the given values.

     The -d flag can be	used to	give an	alternative audio control device, the
     default is	/dev/audioctl0.

     The -n flag suppresses printing of	the variable name.

ENVIRONMENT
     AUDIOCTLDEVICE  the audio control device to use.

FILES
     /dev/audio0     audio I/O device (resets on open)
     /dev/audioctl0  audio control device
     /dev/sound0     audio I/O device (does not	reset on open)

EXAMPLES
     To	set the	playing	sampling rate to 11025,	you can	use
	   audioctl -w play.sample_rate=11025
     To	set all	of the play parameters for CD-quality audio, you can use
	   audioctl -w play=44100,2,16,slinear_le
     Note that many of the variables that can be inspected and changed with
     audioctl are reset	when /dev/audio0 is opened.  This can be circumvented
     by	using /dev/sound0 instead.

COMPATIBILITY
     The old -f	flag is	still supported.  This support will be removed eventu-
     ally.

SEE ALSO
     audioplay(1), audiorecord(1), mixerctl(1),	audio(4), sysctl(8)
