I'm trying to see if I can ever get my microphone to
work. [Actually, I can't get it to work for Skype
(internet phone). This test is just a subproblem,
i.e., to get my microphone to work in general.]
According to "The arecord/aplay Mini-Howto" at
I do the followings:
1) unmute my microphone
2) arecord -f dat -d 20 -D hw:0,0 test.wav
3) aplay -f dat test.wav (not music/test.wav)
While recording, I spoke "testing 1 2 3 4 5 ...".
But while playing (using aplay), I get no sound,
My console screen says
shengchieh $ arecord -f dat -d 20 -D hw:0,0 test.wav
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
shengchieh $ aplay -f dat test.wav
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
The console gives no clue to what is going wrong.
Fyi, the file, test.wav, is 3840044 byte.
What is the problem on why I get no sound while playing?
Am I doing something wrong or something missing?
Thanks in advanced for any help.
