When I click to sound icon on the panel, I have 3 options:

"Mute all" is gray and could not be clicked

Slider - I can slide but it DOESNT change anything

Preferences - Shows this

(waiting for the response from audio
device), but it doesn't show anything
for more than a hour

This is from aplay -l :

root@fb:~# aplay -l
