[xubuntu-users] Pulseaudio failure cripples videos

I had an interesting experience last night. I was watching a TV
episode online and suddenly the sound failed, then the video froze.
At first I thought it was a browser problem (Seamonkey, but then
Firefox and Chrome also did the same thing). This leaked out across
everything on my machine - all other links to that show, then YouTube
would play a video for up to 10-15 seconds and then freeze. I could
restart it by clicking on the progress bar just ahead of the cursor,
and that would go for another few seconds and stop.
Then I tried mplayer, and it was mute as well, though I believe I was
able to stop it.
I tried to log out and back in, and the screen went black. I was able
to log in on the secondary console (<alt><F8>) and log out, but still
Finally I rebooted and poked around in the syslog, and apparently
pulseaudio had some kind of catastrophic failure that caused the
problems. (Everything worked after I rebooted.)
Question: Is there a way, other than rebooting, to recover the audio
(and correlated video) problems in this case when pulseaudio dies? Is
there a simple alternative to pulseaudio that "just works?"
I'm running Xubuntu Precise LTS (12.04) with the Raring kernel (3.8).
This may be part of the issue, but I expect the underlying kernel not
to be a problem with legacy apps and drivers.
