[Gumstix-users] Record USB Audio on Overo AirStorm + Summit board

[JonDoe <ame...@ya...>]

Hi,

I am trying to record audio from a USB microphone on the AirStorm board.
However I cannot get any signal when I use arecord for recording sound. I
tested the file on my computer to get no audio signal during playback.

I tried to play an existing .wav file but I got no sound output either. The
.wav file is confirmed working on another computer with working audio
playback.

I am using the command arecord -f cd -d 10 test.wav. The command will run
for the 10 seconds and exit as if normally, but the clip itself contains no
audio information.

I have not installed any drivers/additional softwares on the gumstix. I was
using the factory preinstalled Agstrom kernel (running opkg upgrade just
now). 

Do I have to make any configuration changes/ install any drivers before I
can get audio working? Or should arecord work out of the box?

Thanks,
Ameya
