Alsa Driver Issue


I am using Rev B5 Beagle Board. I am trying Audio Playback on Beagle board.arecord -t wav -c 2 -r 44100 -f S16_LE -v k is diplaying on the console according to the Beagle test diagonistics.
But while playing Audio output is not coming out. However aplay is playing pcm data which I took from ALSA FS.
Beagle board is not capturing audio from microphone. What may be the fix?

Hi Vineet :

Do you try to use line in from other audio source instead of
microphone. There should be no microphone bias voltage connected to
the audio in connector. I also try the same thing as you did with line
in instead of microphone. It only work on the the aplay and arecord
only record noise. Anybody know the reason?
