The plugins themselves won't show up, in my case it just said firefox
was using it. And I recall getting audio from flash earlier in the
day so thought it still might be using it, and I happened to be right,
after disabling the plugin the lock on the device was released.

Since nothing is using the sound device, I'm not sure what else to
check, short of permissions, at one point a few years ago it wasn't
uncommon for the permissions of devices such as sound devices etc
to get automatically changed to the person logged in. Not sure what
caused it or why, or if anything still does it anymore. But if your
user doesn't have access to the device I would think similar behavior
would occur.

So, check permissions on /dev/snd/* and /dev/dsp, another thing I do
to test is run a command line program that generates a sound(I
use mpg123 out of habbit which plays mp3 files), and see if you
notice any permission denied type errors.
