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, surround left, surround right, and center chan-
           nels. The low frequency effects channel is not tested.


     -7    Surround sound mode (7.1). The test checks  the  left,
           right,  surround  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 supported 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.
