Does the 360 have a sound card?

I have an elite, and the mic constantly goes in and out. I tried replacing the mic, and controller, but it still continues. Could it possibly be the 360 itself? Like a malfunctioning soundcard?

Try a wireless headset.

It's probably your 360

Would that be under warranty? Could you send it in for repairs for that?
