11
12 DESCRIPTION
13 The audiotest utility runs a test for the named audio device (or all
14 audio devices found on the system if none is given). The test includes
15 playing an audio sample over each channel and measuring the rate of
16 playback for clock drift.
17
18 OPTIONS
19 The following options are supported:
20
21 -1
22 Loop mode. The test is run in an infinite loop.
23
24
25 -2
26 Stereo (2-channel) mode. This is the default mode. Playback
27 assumes 2 channels are present.
28
29
30 -4
31 Quadraphonic mode (4-channel surround). The test assumes that
32 four surround channels are present.
33
34
35 -5
36 Surround sound mode (5.1). The test checks the left, right,
37 surround left, surround right, and center channels. The low
38 frequency effects channel is not tested.
39
40
41 -7
42 Surround sound mode (7.1). The test checks the left, right,
43 surround left, surround right, back surround left, back surround
44 right, and center channels. The low frequency effects channel is
45 not tested.
46
47
48 OPERANDS
49 dev
50 The path the device to test, for example, /dev/dsp0.
