I've had this crackling sound problem on my old laptop with 8.04, 8.10, and now with 9.04 as well. Most audio playback is audible but produces a crackling sound. Skype doesn't do this; nor do some videos.

I thought I would find the solution here:

but am unsure. The soundcard seems to be VIA 8233, which I can't find too much about // just these but also can't figure out what to do for my particular machine:

Not at all sure how I should proceed, can anyone advise?

Thanks.
