I think I have the same problem. I am on amd64 proper and I installed flashplugin-nonfree 9.0.48.0.2+really0ubuntu12.2 (from proposed-updates, I guess?)
I get an insane amount of these error messages, and no sound:
ALSA lib ../../../src/pcm/pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave
ALSA lib ../../../src/pcm/pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave
ALSA lib ../../../src/pcm/pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave
ALSA lib ../../../src/pcm/pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave
Based on http://ubuntuforums.org/showthread.php?p=4289792 I am speculating that the source of the problem is in Firefox, not in Adobe's Flash player, though I'm prepared to stand corrected on that.
I also have Nvidia drivers, in case that it significant. I thought I saw mention of those in the Forum posts too.
