17 The \fBaudiotest\fR utility runs a test for the named audio device (or all
18 audio devices found on the system if none is given). The test includes playing
19 an audio sample over each channel and measuring the rate of playback for clock
23 The following options are supported:
30 Loop mode. The test is run in an infinite loop.
39 Stereo (2-channel) mode. This is the default mode. Playback assumes 2 channels
