-tpink means use pink noise (default).
\fB\-t\fP | \fB\-\-test\fP \fBpink\fP|\fBsine\fP|\fBwav\fP
\fB\-t pink\fP means use pink noise (default).
Pink noise is perceptually uniform noise - that is, it sounds like every frequency at once. If you can hear any tone it may indicate resonances in your speaker system or room.
Pink noise is perceptually uniform noise -- that is, it sounds like every frequency at once. If you can hear any tone it may indicate resonances in your speaker system or room.
-tsine means use sine wave.
\fB\-t sine\fP means to use sine wave.
-twav means to play WAV files, either pre-defined files or given via -w option.

\fB\-l\fP | \fB\-\-nloops\fP \fBCOUNT\fP
Specifies the number of loops. Zero means to run inifintely.
When \fB\-s\fP option below with a valid channel is given, \fBspeaker\-test\fP will perform
always a single-shot without looping.

\fB\-s\fP | \fB\-\-speaker\fP \fBCHANNEL\fP
Do a single-shot speaker test for the given channel. The channel number starts from 1.
The channel number orresponds to left, right, rear-left, rear-right, center, LFE,
side-left, side-right, and so on.
For example, when 1 is passed, it tests the left channel only once rather than both channels
with looping.
