Try running "pulseaudio -vvvv" in a terminal. It might explain what is
going on. (do a pulseaudio -k first to stop a running instance first).

Some graphics drivers (nvidia closed source crap) break process
scheduling in some way whcih causes PA to miss its scheduling deadline
which results in drop-outs.
