Moved this thread outside this sticky, where it didn't belong in the first place - apologies for that:

I would file a bug on Launchpad, since this is a regression.
You could also continue with 11.04 for as long as it is supported. It is not uncommon that the second-latest Buntu release is superiour to the latest.
The key might be in editing the alsa-base.conf file, but the problem is finding the right definition. I've posted a similar question in the Panasonic Toughbook forums, will report here if that produces anything.

Unless I can find a solution, I may restort to cutting the speaker altogether by disconnecting it (not too hard in a Toughbook) and reconnecting it once it's possible. I don't like audio feedback anyway, and I rarely use it for other purposes.
Desperate times call for desperate measures, so I disconnected the speaker. The problem is gone for now, but so is my speaker. I'll return to the issue it when I move to 12.04, because a solution for 11.10 doesn't look likely in the near future.
