Title:
  HDMI Audio out fails on Geforce 8200 (MCP78)

Status in “linux” package in Ubuntu:
  New

Bug description:
  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)
