The sound is ok in kernel version "3.0.0-1-686-pae" but on all newer
versions there are sparkling/farting noises coming out of the speaker.
The noise is not very loud, its barely noticeable, but its repetative
and doesn't go away. And I think it happens while typing on the
keyboard and a bit later, then it dissapears for a few seconds,
or by the time that I type again.

I tried running alsa-info.sh as a "user".
I tried 3.0.0-1-686-pae here is the debug:

Being booted into this version for 15 minutes, it seems to not make any noises,
but I will resubmit the info later if the noises will start to appear.

Because the noise is barely heard, I would need to find a good mic.
to be able to record it, but I could do that in the next bug submission.

I might try that, if there are any manuals around how to do it,
but my response might take some time.
