Well, is any of this helpful? Looking in the system log, I find these entries:

04/05/11 04:51:49 PM spectrum2 pulseaudio[4670] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write!
04/05/11 04:51:49 PM spectrum2 pulseaudio[4670] alsa-sink.c: Most likely this is a bug in the ALSA driver ‘snd_hda_intel’. Please report this issue to the ALSA developers.

04/05/11 06:53:45 PM pulseaudio[3043] last message repeated 5 times
This stuff was repeated on April 5, 6, 7, 8 and 9 as I was having trouble with the sound and running the Start script multiple times.
I also got this one today:
04/09/11 06:19:45 PM spectrum2 kernel [366096.159448] pulseaudio[17574]: segfault at 7fcabb8b0080 ip 00007fcabb8b0080 sp 00007fff06bd2878 error 14 in pulse-shm-2246405270[7fcabbed6000+4001000]
I did a Google search on that and found in an Arch Linux forum a post saying the following:
"My problem, though, is that whenever I open pavucontrol and leave it open for a few seconds, the message “Connection failed: Connection Terminated” appears and PulseAudio segfaults. If I don’t open pavucontrol, everything works fine.
dmesg:
pulseaudio[26919]: segfault at 7fdceb0fb010 ip 00007fdceb0fb010 sp 00007fffee42af58 error 14 in pulse-shm-3705512939[7fdceb71a000+4001000]"
And just now I tried to run pavucontrol and got “connection failed: connection refused” - which is odd because I just ran it a little while ago and it ran fine.
More weirdness: I had exited Kmixer earlier. I just restarted it - and I have completely different mixer control layout! It’s showing controls for HDA NVidia. Presumably that comes from disabling the PulseAudio. Probably that’s why pavucontrol doesn’t work anymore - duh.
Let’s see what happens with the new HDA NVidia channel. Everything is running OK now. I’ll wait until tomorrow and see if anything comes crashing down.
