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. -- No sound with adobe flashplayer 9 in Mozilla https://bugs.launchpad.net/bugs/186726 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
