Title:
  Switched channels on HDMI 5.1 setup  (Nvidia ION)

Status in pulseaudio package in Ubuntu:
  Incomplete

Bug description:
  I've choosen a Surround setup (HDMI 5.1) via sound preferences, and I
  got a problem. Some channels were inverted. I used the Hardware "Test
  speakers' to verify. The center sound was appearing on the rear-left,
  and so on... The only right channels were front-left and front-right.

  After search about this problem on the internet, I found this site:
  
http://www.bunkerhollow.com/blogs/matt/archive/2011/06/18/zotac-nd22-xbmc-hdmi-audio-configuration-in-ubuntu-11-04.aspx

  The first weird thing is that the mentioned file,
  /usr/share/pulseaudio/alsa-mixer/profile-sets/nvidia.conf, doesn't
  exist on my machine, although I don't know if it were supposed to
  exist.

  After search for some similar file, I fixed the problem change the
  file /usr/share/pulseaudio/alsa-mixer/profile-sets/extra-hdmi.conf. I
  did what was suggested, commented the channel-map line and put a new
  one, as follows:

  ;channel-map = front-left,front-right,rear-left,rear-right,front-center,lfe
  channel-map = front-left,front-right,front-center,lfe,rear-left,rear-right

  I'm reporting this because I think there is a way to detected the sound board 
and do it automatically. My board is:
  00:08.0 Audio device: nVidia Corporation MCP79 High Definition Audio (rev b1)

  Just let me know if you need more info!
