Mic not picking up volume on Angstrom installation

Hey,

I recently installed Angstrom and Android on my beagleboard, and I
have been trying to use a mic with a 3.5mm connector on it. Although
the mic works on my laptops installation of linux, it does not
function when plugged into the beagleboard on either Angstrom Linux or
Android.

Does using a mic require an amplifier of some sort? Or what else
should I do to get started?

Thanks!
Oliver

It requires an amplifier. MIC input at BB is more like line-input, not mic.

I had been wondering about this as I wasn't able to record from the Mic on my C3.
Until now I didn't see anything saying this and thought it must have been a bad input, a .wav file played without a problem.

With a USB audio card, it reported not enough bandwidth. I wonder if anyone is using usb audio.

Sid.

Here what Gerald Coley explains:

The microphone needs to be amplified. The audio input is a line in audio, like you get from a PC. A microphone won’t work. Try it using the audio output from a PC first. Then find a way to amplify the audio from the microphone.

I tried using the PC line-in method to verify that the line-in input
is working.
Under Angstrom, the recorder is picking up sound when using PC line-in
method; however, I can't get either speaker or line-in to work under
Ubuntu. Is there a special driver needed for this to work on Ubuntu?
