I just got a macbookpro (mid2009 version) with a new nvidia chipset.
there is no sound at all. neither via the built-in speakers nor via
i tried aplay -D myfile.wav with everything from aplay -L as well.
i also tried a recent snapshot (alsa-driver-20090626.tar.bz2) as well
as gentoo ebuilds alsa-headers-9999 and alsa-driver-9999 (which uses
git to pull recent versions).
so here's a little information i can gather:
$ lspci -s 00:08.0 -v
00:08.0 Audio device: nVidia Corporation MCP79 High Definition Audio
(rev b1) Subsystem: nVidia Corporation Device cb79
Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 23
Memory at d3480000 (32-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: HDA Intel
Kernel modules: snd-hda-intel
i also found a thread about that problem (w/o solution obviously):
hope that's all information necessary.
if i can i'd love to help in some way.
