    I have the same problem , I tried with Ubuntu, Debian and even Gentoo but the problem persists; I think that the module is the problem because in Gentoo compile only the modules what you need...

    I tried with kernel 2.6.32, 2.6.33, 2.6.34, and 2.6.35 all have the same problem..

    my temporary solution, installing jackd... is a audio server... this consumes many resources, but prevents the audio skip... but not all programs can connect to jackd then for audio I use amarok and video I use kaffeine, they can...

    I use the same kernel and audio card as you do and get occasional stutters too, and I agree that it's probably a module issue.

    Code:

    Finally seems to have found something that seems to be the solution ...

    Yesterday a new appeared about a linux patch that increases the response speed applications, an alternative implementation of the concept of this patch was sent to the list of Debian users, this do mention of the steps to make this feature, the important thing is that after testing not only improves the response time of applications but also solved the sound problem might be perhaps the best cpu administration to assign more time to the sound hardware .. . try it...

    Improved scheduling might make the problem occur less often but it won't fix the issue. If I understand correctly some report I found a while back the hardware occasionally reports incorrect values and the driver should be ignoring them. It's been a while since I researched so unfortunately I don't recall where I heard this.
