I really don't like the idea of adding hacks to work around pulseaudio bugs,
particularly since pulseaudio is already only barely acceptable CPU-usage
wise and I suspect this approach may further increase the CPU usage of it.
It might be worth checking if -autosync can handle this already and if not
if it can be extended to cover this issue.
