Bug Description
Binary package hint: alsa-base
I have an MSI laptop with an nVidia chipset. Audio is nVidia HDA (MCP51) with a Realtek ALC883 (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 issues reported in bug #63971 (Acer laptops not working with ALC883). 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). Sound controls show the ALSA mixer as "HDA nvidia" and OSS mixer as "Realtek ALC883".

I applied the patch to the 1.0.12 sources and installed them as described here: http:// www.ubuntuforum s.org/showthrea d.php?t= 322817& highlight= mcp51.
Everything still looks fine, but there's still no sound.
