Comment 42 is what did it for me:
https://bugs.launchpad.net/ubuntu/+source/alsa-
lib/+bug/396558/comments/42
Running:
$ alsamixer
I had:
Card: HDA Intel
Chip: VIA ID 4441
Master at 100
PCM at 0.
Putting PCM up to 100 solved the issue, and sound is working on Flash
with no problems.
Here's my LSB_RELEASE & APT_CACHE output in case someone is wondering:
$ lsb_release -a
