I recently built a HTPC and installed Ubuntu 12.10 on it. It's a Shuttle XH61V with an onboard HDMI connection that I'm using to connect to the TV, which in turn connects to the speaker system (5.1).
I've tried everything I can find on this site and through Google but to no avail. I've even tried installing Ubuntu 13.04, but that seems to present the exact same problem.
pavucontrol
only shows "Digital Stereo (HDMI) Output" but no surround. Running speaker-test -c 6
seems to play to all speakers at once for the front speakers, quieter for the back speakers and not at all for LFE.
Since it's running through HDMI, I don't know if the fact that I'm using Intel HD graphics 4000 comes into play or not.
Here's my output for aplay -L
:

Does anyone have any suggestions? I would be greatly appreciative of any help.
Thank you in advance!
