Public bug reported:
I've tried everything to get this sound working. Headphones work fine,
they're loud and clear, but speakers don't work at all. I've recompiled
from alsa-source. I've recompiled from source files direct from ALSA.
I've tried adding various options in /etc/modprobe.d/alsa-base. Nothing
works.
What's more, alsamixer doesn't work. Whenever I try to run alsamixer, it
spits an error back at me (listed below), so I can't tell if the speaker
channel is just muted or not.
I'm running Kubuntu Hardy Beta, however the same problem occurred in
Gutsy.
