[Bug 476652] Re: sound stops and begins clicking and popping

[feroxy]

Doesn't seem to be any improvement with the lucid liveCD.

Totem is unusable with pulseaudio enabled; after a few minutes, it just
goes silent then starts speeding though the video. Had some crashy
things happen too while testing all this out. gnome-volume-control died,
sound died completely until I did a "alsa force-reload" and restarted
pulseaudio. Generally, not very good. Again, killing pulseaudio seems to
make sound "work" as it does on my 9.10 install (as far as I could
tell).

Got several instances of the following in the syslog, with varying
values:

Apr 26 01:57:54 ubuntu pulseaudio[10056]: alsa-util.c: snd_pcm_delay() returned a value that is exceptionally large: -715420 bytes (-4055 ms).
Apr 26 01:57:54 ubuntu pulseaudio[10056]: alsa-util.c: Most likely this is a bug in the ALSA driver 'snd_cmipci'. Please report this issue to the ALSA developers.
