I had a similar problem capturing the sound via the btaudio-module. I
solved it by setting -tv on:...:audiorate=32000 _and_ -srate=32000. Try
a few other audiorates like 22050, 44100 or 48000.

Capture with a higher resolution (I use 768x576, dropping the
occasional frame) and rescale in a second step ;)
