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

OPTIONS

19       The following options are supported:
20
21       -1    Loop mode. The test is run in an infinite loop.
22
23
24       -2    Stereo (2-channel) mode.  This  is  the  default  mode.  Playback
25             assumes 2 channels are present.
26
27
28       -4    Quadraphonic  mode  (4-channel  surround).  The test assumes that
29             four surround channels are present.
30
31
32       -5    Surround sound mode (5.1). The test checks the left, right,  sur‐
33             round  left,  surround  right,  and center channels. The low fre‐
34             quency effects channel is not tested.
35
36
37       -7    Surround sound mode (7.1). The test checks the left, right,  sur‐
38             round  left,  surround  right,  back surround left, back surround
39             right, and center channels. The low frequency effects channel  is
40             not tested.
