Some more clarification:

1. Starting from ubuntu version 9.10 the system beep has been replaced
from a sound coming from the sound card.
2. If you load the module pcspkr you can ear a sound coming from the pc
speaker but the system don't use it (only at the shut down or with the
beep command)
3. If you load the module snd_pcsp you can ear a beep coming from the
suond card but the system don't use it (only at the shut down or with
the beep command)
4. In my case the sound coming from the sound card was missing (point 1)
and it works only if you disable compiz so I have to understand why
compiz stops that sound.

Any suggestion?
