My only suggestion, from my experience, is to try to do a fresh complete
install, not an upgrade from 8.10.  When I did the upgrade I had the
same problems but after doing a fresh from scratch install of Jaunty my
sound and video work fine.

These anomalies are due to buffering and clock adjustment calculations that incorrectly assume that the underlying hardware is well-behaved.

> Resolution/Fix: Improve the buffering and clock calculations by providing more conservative floors and ceilings. Changes are backported from linux-2.6.git and alsa-kmirror.git. Provenance is given in the commits listed below in the Changesets section. Users have fared well using test kernels from http://kernel.ubuntu.com/~dtchen/.

> Regression potential: Theoretically, there is extremely low probability for regression, as these patches simply remove the assumptions that the underlying hardware is well-behaved. Practically, users of jack-audio-connection-kit (JACK) and other native ALSA apps [not routed through PulseAudio as is the default in Ubuntu] may notice changes in jitter. Testing since Jaunty's release has revealed no regressions.

> I hope this isn't a dupe. A few people (myself included) are experiencing odd crackling / scratching noises when using pulseaudio. This frequently happens when you try to start a new piece of music or video. Sometimes it will crackle for a few seconds, then play as normal; sometimes it will fast-forward through a few minutes of the song then start playing; sometimes it will crackle then stop entirely and I have to kill pa.
