I have an XFX Geforce 8200 (MCP78) motherboard. While HDMI video out works fine, HDMI audio doesn't work with the 3.8 kernel (3.8.0-29 or 3.8.0-34), I've tried with both the nouveau and nvidia binary drivers.  The analog outputs work with either driver.  
After upgrading to kernel  3.11.10-031110-generic, from the kernel mainline PPA, and using the nouveau drivers I'm able to get audio out over HDMI, using the following options in /etc/modprobe.d/alsa-base.conf: 
options snd-hda-intel single_cmd=1 probe_mask=-1,0x8 unmute iec958

While using this configuration, I have audio and it's mostly stable,
however, I'm unable to take advantage of 3d acceleration and HD video
playback is choppy.  If I then use the any of the nvidia drivers (304,
319, 331, or current) I get frequent crashes, including system lockups.
I have confirmed with VLC, mplayer2, and speaker-test that no audio
comes out through HDMI until the 3.11 kernel, nouveau drivers, and the
modprobe options mentioned are all in place.

I'm attaching  20131228_logs.zip containing the output of: 
aplay -lL (aplay_out)
lspci -k  (lspci_out)
and the following additional files: 
dmesg 
dmesg.0
lsb-release

uname -a  returns: 
Linux DVR 3.11.10-031110-generic #201311291453 SMP Fri Nov 29 19:54:20 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
This is the kernel that has working audio but is unstable with the nvidia binary in use (and choppy hd playback with nouveau)
