Public bug reported:
Internal Speaker does not work (whether external speakers are plugged in
or not), and External Speakers do not work either. I can't get any sound
to work. I was peviously using 10.04 LTS and decided to try the 12.04
alpha. My sound was working in 10.04 even though both the internal
speaker and external speaker output sound at the same time (so i
unplugged the internal speaker as a easy solution). I plugged the
internal speaker back in for this test since i could get no sound from
the external one, but niether seem to work.
Relevant results from 'lspci':

I tried using apport, but it also says that 'alsa' and 'alsa-driver'
does not exist. Maybe thats the problem? Since there was at least some
functionality in 10.04 with Gnome, i'm assuming that this is either a
regression or something is not installed correctly.
