Update: If CPU% is too high, sounds become choppy and won't recover
until the application close and reopen (therefore the audio device is
re-inited).

just for comparison, I tested on Dell Latitude 2110 with Atom N470 CPU,
I do not observe the same issue with PulseAudio 0.99.3-0ubuntu5.

More:
If CPU% is too high AND AUDIO BUFFER TOO SHORT (say 10ms e.g.), sounds
become choppy. If the buffer isn't too short, audio playback is still
fine even if I run another application to consume all available CPU
resource.
PS: I've upgraded to the latest Oneiric, with pulseaudio version
1:0.99.
My Toshiba N205 works fine when CPU% doesn't reach ~100%. But when CPU
is busy (e.g. during chatting with IM SW, the sound sometimes become
choppy. The speaker-test works fine also.

I dare say that this one is going to be there on the final
release...Sad,, cause its a major issue. I'm really curious if that
affects other Atom users. Kubuntu and removal of PA will be my last
shelter, given the GPU situation.

Can say that I never had any audio issue on this netbook from Hardy Heron 8.04.
Quite sad to have this now, we already have a lot of issue with gfx drivers!

Shouldn't the cause be found among the changes from the changes from the
last working version to the first buggy one? In case you have a clue
and want some testing, tell me, ciao!

Okay, then I don't have any good ideas at the moment. Probably need to
have a very low-end machine in order to dig deep enough into the
problem.

OK, I'm using Kubuntu right now with latest updates (inc. PA). The
result of "paplay" is the same "skipping rewind" behaviour.

Hi Simply Gades and thanks for testing the new PulseAudio version!
Seems you get stuck in eternal rewinding, which is one of the bugs I've
trying to work with this cycle. Unfortunately, it's quite hard to fix
it.
Do you still get the same breakups if you're using any of these commands
to play bac
