I have tried all the measurements above, but they all failed.
ALSA seems working, and my sound panel is on a normal mode. Still no sound out by recording voice from a recorder or skype echo test...
BTW, the version of my skype is 2.1.0.81.

cat .servers | while read LINE; do
ssh jason@$LINE $1
done
exit 1
./command.ksh "ls -l ~jason"
Why does this ONLY iterate on the first server in the list? It's not doing the command on all the servers in the list, what am I missing?
Thanks!

Hi. I've been playing around a bit. This isn't for any practical purpose-- it's really just a theoretical exercise. I wrote this little thing:
foreach num ( 6 5 4 )
awk -v "number=$num" 'BEGIN{for(x=0;x<$number;x++) printf "-"; printf "\n"}'
end
I would expect the following output:

Hi!
I have a somehow big file (almost 3000 lines long and thirteen columns). Some lines have no value at all or, at least, are incomplete. The columns' values that have no data are marked with a "-" and the corresponding line (the line that owns that value) should be discarded and not used.

speaker-test
SPEAKER-TEST(1) General Commands Manual SPEAKER-TEST(1)
NAME
speaker-test - command-line speaker test tone generator for ALSA
SYNOPSIS
speaker-test [-options]
DESCRIPTION
speaker-test generates a tone that can be used to test the speakers of a computer.
OPTIONS
-c | --channels NUM
NUM channels in stream
-D | --device NAME
PCM device name NAME
-f | --frequency FREQ
sine wave of FREQ Hz
--help Print usage help
-b | --buffer TIME
Use buffer size of TIME microseconds. When 0 is given, use the maximal buffer size. The default value is 0.
-p | --period TIME
Use period size of TIME microseconds. When 0 is given, the periods given by -P option is used. The default value is 0.
-P | --nperiods ERIODS
Use number of periods. The default value is 4.
-r | --rate RATE
stream of RATE Hz
-t | --test pink|sine|wav
-t pink 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 indi-
cate resonances in your speaker system or room.
-t sine means to use sine wave.
-t wav means to play WAV files, either pre-defined files or given via -w option.
You can pass the number from 1 to 3 as a backward compatibility.
-l | --nloops COUNT
Specifies the number of loops. Zero means to run infinitely.
When -s option below with a valid channel is given, speaker-test will perform always a single-shot without looping.
-s | --speaker CHANNEL
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.
-w | --wavfile
Use the given WAV file for the playback instead of pre-defined WAV files.
-W | --wavdir
Specify the directory containing WAV files for playback. The default path is /usr/share/sounds/alsa.
USAGE EXAMPLES
Produce stereo sound from one stereo jack:
speaker-test -Dplug:front -c2
Produce 4 speaker sound from two stereo jacks:
speaker-test -Dplug:surround40 -c4
Produce 5.1 speaker sound from three stereo jacks:
speaker-test -Dplug:surround51 -c6
To send a nice low 75Hz tone to the Woofer and then exit without touching any other speakers:
speaker-test -Dplug:surround51 -c6 -s1 -f75
AUTHOR
The speaker-test program was written by James Courtier-Dutton. Pink noise support was added by Nathan Hurst. Further extensions by
Takashi Iwai.
