Binary package hint: pulseaudio
Kubuntu 10.10 64bit. I was having some audio problems since upgrading to 10.10 from 10.04. I got sick of it and did a fresh install. Total wipe of the drive and reinstall from cd. Originially when I had this problem, I was using a Creative X-Fi PCI SB0730 (XtremeGamer I believe). I was getting a lot of "pulseaudio[1641]: ratelimit.c: 22715 events suppressed" in /var/log/messages.
pulseaudio:
Installed: 1:0.9.22~

I saw some others were having trouble and needed the pulseaudio logs. I did get one while I was having the trouble, I'll try to post that.
Note: I've since removed the X-Fi and am using a Diamond Monster Sound ES1968 PCI card. On first boot, things seemed fine. KDE sounds were fine and I even watched a <2 mins YouTube vid with no trouble. I then opened VLC and was playing a song, about 75% through the song, sound was cutting out. Skipping and the whole system became very slow and almost unresponsive. Once I closed VLC (kill) everything came back... except sound. Now, even after rebooting, sound is sporadic. That's why I believe this is a pulseaudio problem and no something specific to the X-Fi.

Pretty much anything that uses sound, makes the system almost unresponsive. If I tail -f /var/log/messages when this happens, I start seeing the pulseaudio ratelimit repeating. Several times I've seen 5 events suppressed. I've seen a couple thousand events suppressed, I've seen over 20,000 events suppressed in one line.
Oh, FYI... If I use VLC and tell it to use ALSA directly, there's a few skips here and there. But for the most part, it's acceptable. My uneducated guess is ALSA is skipping (rare, and not all the time) and pulseaudio doesn't know what to do and pukes.
If you are interested, I've had some troubleshooting done by a forum member here: http://
