I just got my iPad2 yesterday so this may be an easy fix but I have no idea what happened. I used FaceTime this afternoon and it worked fine. I was using it again just now and it started fine and then the sound started to cut in and out and then finally stopped Altogether. They could still hear me but I couldn't hear them anymore. We tried hanging up and calling again but it made no difference.
Any suggestions on what to try would be appreciated!
