Bug Description
Binary package hint: linux-image-
The audio output is not smooth with the newest kernel included in the karmic. With the 2.6.30.1 kernel everything is ok.

I am facing similar problems with sound output on a 810E intel chipset based desktop with CM8738 onboard sound card. In my case sound stutters initially and after a few minutes it drops totally. The commandline music player 'music123' shows a "buffer underun error" when the sound is stopped. I tried different fragment size settings in '/etc/pulse/ daemon. conf ' but none worked.
Music plays perfectly when the sound is channeled through the 'OSS output plugin' which is found in the settings of VLC, audacious and mplayer .
The issue had come up during the development cycle of jaunty: https:/ /bugs.launchpad .net/pulseaudio /+bug/345627 and the issue had supposedly been fixed by including this patch: https:/ /lists. ubuntu. com/archives/ kernel- team/2009- April/005405. html
Most probably there is a problem with pulseaudio + alsa 1.0.20 combinaton, see the comments section here(0021081): https:/ /bugtrack. alsa-project. org/alsa- bug/view. php?id= 4642
