BugLink: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=620513 From the Debian bug report: "The speaker-test manpage could be improved somewhat by helping a little bit the user determine how to find out the devices he can test. Based on http://alsa.opensrc.org/Speaker-test I have make some changes to the manpage (diff attached) to describe a little bit more how speaker-test can be used alongside 'aplay'. Please consider the following patch for alsa-utils-1.0.23/speaker-test/speaker-test.1" Signed-off-by: Javier Fernández-Sanguino Peña <jfs@debian.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

.TH SPEAKER\-TEST 1 "April 2nd, 2011" speaker-test
|
|
.SH NAME
|
|
speaker\-test \- command-line speaker test tone generator for ALSA
|
|
.SH SYNOPSIS
|
|
.B speaker\-test [\-options]
|
|
|
|
.SH DESCRIPTION
|
|
\fBspeaker\-test\fP generates a tone that can be used to test the speakers of a computer.
|
|
|
|
\fBspeaker-test\fP by default will test the \fIdefault\fP device. If you
|
|
want to test another sound device you will have first to get a list of
|
|
all of the sound cards in your system and the devices associated with
|
|
those cards. Notice that there might be for example, one device for
|
|
analog sound, one for digital sound and one for HDMI sound.
|
|
To get the list of available cards and devices you can run \fBaplay -L\fR.
|
|
|
|
.P \fBaplay\fR's output will be similar to this one:
|
|
|
|
.nf
|
|
$ aplay -L
|
|
null
|
|
Discard all samples (playback) or generate zero samples (capture)

|
.P Each of the devices is listed in the beginning of the definition so,
|
|
in the above example, there are four devices listed: null, default, front
|
|
and surround40. So, if you want to test the last device you can
|
|
run \fBspeaker-test -Dsurround40:ICH5 -c 6\fR. The \fB-c\fR option will
|
|
indicate that the six audio channels in the device have to be tested.

.TP
|
|
\fB\-b\fP | \fB\-\-buffer\fP \fITIME\fP
|
|
Use buffer size of \fITIME\fP microseconds.
|
|
When 0 is given, use the maximal buffer size.
|
|
The default value is 0.
|
|
|
|
.TP
|
|
\fB\-p\fP | \fB\-\-period\fP \fITIME\fP
|
|
Use period size of \fITIME\fP microseconds.
|
|
When 0 is given, the periods given by \fB\-P\fP option is used.
|
|
The default value is 0.
|
|
|
|
.TP
|
|
\fB\-P\fP | \fB\-\-nperiods\fP \fPERIODS\fP
|
|
Use number of periods. The default value is 4.
|
|

|
.TP
|
|
\fB\-r\fP | \fB\-\-rate\fP \fIRATE\fP
|
|
stream of \fIRATE\fP Hz

|
|
.TP
|
|
\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.
|
|
|
|
\fB\-t sine\fP means to use sine wave.
|
|
|
|
\fB\-t wav\fP means to play WAV files, either pre-defined files or given via \fB\-w\fP option.
|
|
|
|
You can pass the number from 1 to 3 as a backward compatibility.
|
|
|
|
.TP
|
|
\fB\-l\fP | \fB\-\-nloops\fP \fBCOUNT\fP
|
|
|
|
Specifies the number of loops. Zero means to run infinitely.
|
|
|
|
When \fB\-s\fP option below with a valid channel is given, \fBspeaker\-test\fP will perform
|
|
always a single-shot without looping.
|
|
|
|
.TP
|
|
\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 corresponds 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.
|
|
|
|
.TP
|
|
\fB\-w\fP | \fB\-\-wavfile\fP
|
|
Use the given WAV file for the playback instead of pre-defined WAV files.
|
|
|
|
.TP
|
|
\fB\-W\fP | \fB\-\-wavdir\fP
|
|
Specify the directory containing WAV files for playback.
|
|
The default path is \fI/usr/share/sounds/alsa\fP.
