# 8  
Old 07-22-2009
I did try with my old input only. But there is some change in the input file. I think i need to use port/channel in the first line of the test.awk file.
Code:
if ($0 ~ /Port/) {date1=substr($1,1,index($1,"(:") - 1)}

Thanks for your help

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.
