Public bug reported:
Binary package hint: alsa-base
I have an MSI laptop with an nVidia chipset. Audio is nVidia HDA with a
Realtek ALC833 (Azalia) chipset back-end. All of the hardware is
detected perfectly and all of the application appear to see the hardware
and be working fine, but I have no sound. Yes, I've been through all of
the volume & sound configurations and everything is turned up and no
muted. I've even double-checked the gui with alsamixer. No sound from
the speakers or headphones. Behavior is very similar to the isues
reported in bug #63971 (Acer laptops not working with ALC833). I haven't
been able to try the upstream fix in 1-0-14rc1, because even when the
packages compile nad install fine, Gnome won't initialize properly after
they've been installed (hangs at splash screen).
