Over the network, i.e. with a remote PULSE_SERVER set, I get a lot of
rewinds when a stream is playing. The frequency is high, in the 2-4 Hz
range. Acoustically it sounds like about three fadeouts per second, as
if someone would move a fader up and down all the time. I have Kernel
2.6.27-3 and PA 0.9.12. The log looks like this:


D: sink-input.c: Have to rewind 368 bytes on render memblockq.
I: module-alsa-sink.c: Underrun!
D: protocol-native.c: Requesting rewind due to end of underrun.
D: module-alsa-sink.c: Requested to rewind 37968 bytes.
D: module-alsa-sink.c: Limited to 272 bytes.
D: module-alsa-sink.c: before: 68
D: module-alsa-sink.c: after: 68
D: module-alsa-sink.c: Rewound 272 bytes.
D: sink.c: Processing rewind...

I’m unsure if the frequency somehow correlates with this:

D: alsa-util.c: Maximum hw buffer size is 371 ms
[...]
I: module-alsa-sink.c: Using 1 fragments of size 65536 bytes, buffer time is 
371.52ms
