Using bigger buffers should help. I guess the auto-detecting modules
don't support changing the buffering, so change the default.pa to use
the module-alsa-sink, and give it fragments and/or fragment_size
parameters (see http://www.pulseaudio.org/wiki/Modules ). I'd start with
growing the fragment_size parameter (the default fragments value seems
to be quite high already).
