I'm not sure the problem is 100% on pulseaudio side. It looks like pulsesink
doesn't wait for the uncork to be completed (when I set wait to TRUE it just
hangs?!). I see the first latency_update with a non-zero read index coming in
~120ms after the uncork is initiated (which is done on the first write). This
looks reasonable to me, assuming that pulseaudio gets the automatic timing
update every 100ms.

I'm starting to think that maybe pulseaudio cannot provide accurate timing
because it should not. Wouldn't it be more logical that clock drift
compensation would be done in pulseaudio itself?
