Public bug reported:

Binary package hint: pulseaudio

One of my machines, that never had audio problems with previous Ubuntu
versions, renders audio playback unusable with Lucid. It keeps
skipping/rewinding playback and it doesn't matter what program do I use
or even what kind of media file.

With PA debug watching, I get such output when it starts skipping audio:

D: alsa-sink.c: Wakeup from ALSA!
I: alsa-sink.c: Underrun!
I: alsa-sink.c: Increasing wakeup watermark to 50,00 ms
D: protocol-native.c: Underrun on ''The Racing Rats' by 'Editors'', 0 bytes in 
queue.
D: protocol-native.c: Requesting rewind due to rewrite.
D: alsa-sink.c: Requested to rewind 39124 bytes.
D: alsa-sink.c: Limited to 6836 bytes.
D: alsa-sink.c: before: 1709
D: alsa-sink.c: after: 1709
D: alsa-sink.c: Rewound 6836 bytes.
D: sink.c: Processing rewind...

D: alsa-sink.c: Limited to 7036 bytes.
D: alsa-sink.c: before: 1759
D: alsa-sink.c: after: 1759
D: alsa-sink.c: Rewound 7036 bytes.
D: sink.c: Processing rewind...
D: sink-input.c: Have to rewind 7036 bytes on render memblockq.
D: sink-input.c: Have to rewind 14072 bytes on implementor.
D: source.c: Processing rewind...

And it goes on and on and on, until at some point it plays ok for few
minutes, then starts skipping again.

It also doesn't matter if I do something else or I play music with all
other programs closed.
