Have you tried the -rt kernel available from Ubuntu (in Synaptic) to see if it helps?

Number 9, number 9. Fedora 9 Preview has been cleared for takeoff! Posted Apr 19, 2008 10:15 UTC (Sat) by kripkenstein (subscriber, #43281) [Link] To be honest, fiddling with kernels and kernel options isn't really my area of expertise, I don't feel comfortable doing it. More likely I'd mess something else up than fix anything. Part of this is the reason why I like Ubuntu, things generally work out of the box. But not this time.

No fiddling required! Worth 10 minutes to test I would suggest :-)

Audio stutter and the -rt kernel Posted Apr 19, 2008 18:21 UTC (Sat) by Felix_the_Mac (guest, #32242) [Link] Well, I'm sorry to hear that. I should say at this point that I am nothing more than an -rt fanboy and don't have much knowledge on the subject. So take anything I say with a grain of salt and I would welcome correction from more knowledgeable readers. I have often wondered whether the mere act of running the -rt kernel will provide a more responsive system albeit with lower total throughput (and pondered whether it should therefore become the default desktop install). Or whether, on the other hand, to gain appreciable benefit you have to: a) have a workload suited to its purpose b) tune your system (primarily through nice) to produce benefits. The single data point that you have provided me with leans to the second position. (Unsurprisingly) So to give you some more of my ignorant suggestions ... to address your problem maybe you need to run PulseAudio with a priority above the default. Potentially that could work on the standard kernel and/or -rt kernel. Have you tried nice?
Audio stutter and the -rt kernel Posted Apr 19, 2008 18:25 UTC (Sat) by kripkenstein (subscriber, #43281) [Link] No, I didn't try nice or any other priority tinkering. Mainly because I'm not really knowledgeable about the fine details. But also because I presume that if this were a simple case of changing priorities, then the bug could be fixed, but people have worked hard to no avail (judging by the comments).
