Hi, I'm having this problem too, after upgrading from Lucid to Maverick. Tried to install newer alsa drivers from alsa site, but somehow it didn't worked (I hadn't sound at all), so I restored default Ubuntu configuration.
Just added "options snd-hda-intel model=intel-alc889a" to /etc/modprobe.d/alsa-base.conf Now, I've tried to compile kernel from linux-source with the same modules currently installed and the issue persisted. I have seen in both cases this kind of output in /var/log/messages when skips occur: Feb 3 00:38:53 PHENIIX4TMP1 pulseaudio[2372]: ratelimit.c: 20 events suppressed This is with kernel 2.6.35-25. I've installed a newer kernel from Ubuntu Kernel team, 2.6.35-26, and now there are less pulseaudio logs, but the issues(skips) are still present. I've tried with mp3, wma and m4a (verified) files and youtube vids., and all of them have the same problem. I have even tried aplay /usr/share/sounds/KDE-Im-Phone-Ring.wav and I got 4 pulseaudio lines (and their respective skips)! So it can't be related to decoders. That wav file had 4 skips during its about 2 seconds playback.
