It would be interesting to see:
* which distributions people are having issues with;
* which sound cards and alsa drivers people are having issues with;
* which version of alsa, linux-kernel and pulseaudiio they are
using (plus any other relevant systems);
* which programs are playing up and in what configurations;
* what usage patterns are causing issues.
For the record, sound was for me on Ubuntu 9.04, but I kept
experiencing intermittent sound glitches/periods of silence. This is
using the snd-hda-intel driver on a HP Pavillion dv9000. I can't
confirm it working on current 9.10 as I switched to OSS4 and the
upgrade broke everything (reinstalling alsa worked; not tried PA yet).
I suspect that the issues may have been made worse as a result of
intensive/demanding computer use (e.g. listening to music while
compiling and browsing the web). This may be better in 9.10 (it is
definitely a lot snappier) with the use of Con Colvas' scheduler,
When I get around to re-installing 9.10 (probably some time after
release), I will post my experiences here and coordinate with upstream
packages and Ubuntu to help resolve the issues (if there are any),
without doing a knee-jerk "remove pulseaudio" reaction.
