I was so hoping that the PA on Ubuntu Lucid was going to be much more stable than previous releases but alas, I don't think it's to be. Currently installed on a machine here is 0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu14 which presumably is some form of 0.9.22. I have it currently running with "-vvvv" due to the instability and desire to at least log what it's doing. As such, I can provide a full log upon request. But currently, at this moment, there is not even any audio running through it and it's using 90% of a pretty modern (and hence, somewhat beefy) processor. The only thing the log is showing currently, while this is happening: D: module-rtp-recv.c: Checking for dead streams ... W: ratelimit.c: 3267 events suppressed I: alsa-source.c: Overrun!
