We are debugging a new QEMU USB audio model that works fine with alsa
backend but drops samples from time to time with pulseaudio backend.
Traces show that the pa_simple_write() call normally does its job
quickly

Greetings,
We are debugging a new QEMU USB audio model that works fine with alsa
backend but drops samples from time to time with pulseaudio backend.
Traces show that the pa_simple_write() call normally does its job
quickly, but sometimes takes ~60ms to return (the last write=XXms
field):
Hi Lennart,
We found that pulseaudio eats CPU ~19% CPU time, a little more than
mplayer when playing video. This is horrible for laptop batteries.
Can we make it just work -- in green CPU mode? I can find many users
complaining about this, and it seems like some fix is available in
this link:
