Public bug reported:

Ubuntu 11.10
hp notebook dv6


When playing sound in firefox flash player, I can't use other sound app
(sound is muted). Only flash player "speaks". Furthermore, flash player
is not listed in Applications list of sound settings (as it was in
ubuntu 11.04).

However if I read HTML5 sound/video in firefox, it works properly (only
flash make sound system bugs).
