I had a similar problem... It resulted from the backend not being able
to get audio data (for syncing, I think).

check the console where you start the backend for error messages.

remember that the user running the backend must have R/W permissions to
/dev/dsp.

With the ivtv drivers, the backend doesn't touch /dev/dsp at all, since
there's absolutely no need for it to.
