Public bug reported:

After a fresh installation of Ubuntu 10.10 on my laptop, I can't hear
any sound. On "sound preferences", the microphone seems to be working,
but there's no output sound neither from the internal speaker nor from
the headphones if I connect them.

If there's any more information I can provide, just tell me.
