alsa recording

I am running 2.6.22 kernel with alsa audio driver on beagleboard.
I have writen API for playback and record.
playback is working for downloaded .pcm files but it is not working for my recorded data.
Please any one knows how to record let me know.


Hi choudhary,

Its working fine. Thanks…

Just to make it clear for everybody.

The audio-in on Beagle is a “line-in” input and not a “microphone” input,

which have much lower amplitude and normally as well requires some kind of bias supply…

This is why you didn’t have any luck connecting the microphone directly to the Beagle…

In case microphone support is needed you need a pre-amplifier/biasing circuit between the Beagle and the microphone…

Best regards
