NAME
       audiotest - test audio device

SYNOPSIS
       audiotest [-24571] [dev] ...

DESCRIPTION
       The  audiotest  utility	runs a test for the named audio device (or all
       audio devices found on the system if none is given). The test  includes
       playing	an  audio  sample  over each channel and measuring the rate of
       playback for clock drift.

OPTIONS
       The following options are supported:

       -1    Loop mode. The test is run in an infinite loop.

       -2    Stereo (2-channel) mode.  This  is	 the  default  mode.  Playback
	     assumes 2 channels are present.

       -4    Quadraphonic  mode	 (4-channel  surround).	 The test assumes that
	     four surround channels are present.

       -5    Surround sound mode (5.1). The test checks the left, right,  sur‐
	     round  left,  surround  right,  and center channels. The low fre‐
	     quency effects channel is not tested.

       -7    Surround sound mode (7.1). The test checks the left, right,  sur‐
	     round  left,  surround  right,  back surround left, back surround
	     right, and center channels. The low frequency effects channel  is
	     not tested.

OPERANDS
       dev    The path the device to test, for example, /dev/dsp0.

BUGS
       audiotest has no way to detect the number of actual audio channels sup‐
       ported by the physical device.

       audiotest does not test the low-frequency effects (LFE) channel.

       There is no test for audio capture, volume controls, or other  advanced
       device features.
