Thanks for the information, the issue was really in ao_pulse which did
not set the "ao_data.outburst", which caused this sleep here to be far
too short.
Should be fixed in r34726, though it is just a guess since I did not
find any pulseaudio function to get a really "correct" value as we do
for ALSA.
