Binary package hint: pulseaudio
After I installed Ubuntu 9.10 I noticed a many log messages from pulseaudio in "user.log" section from System Log Viewer:
Nov 7 12:20:07 ubuntu pulseaudio[1440]: ratelimit.c: 16 events suppressed
Nov 7 12:20:12 ubuntu pulseaudio[1440]: ratelimit.c: 13 events suppressed

Nov 7 13:36:00 ubuntu pulseaudio[1441]: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_via82xx'. Please report this issue to the ALSA developers.

Nov 7 14:20:51 ubuntu pulseaudio[1441]: ratelimit.c: 91 events suppressed
This is just part of the log. There are a lot of similar messages.
Besides that I also noticed that pidgin sounds flicker. If I remove pulseaudio package the sounds stop flickering as well as those log messages.
And what means "ratelimit.c: xx messages suppressed" ? Is this bad?

Same here. My problem is that front mic stops working.
