I've only been able to get 5.1 audio with movies, but I verified that I can send signals to all 8 speakers independently using W7's built in speaker config screen, as well as verifying that my receiver sees all 8 speakers accordingly. However, the real problem could lie with the video encode I was using (even though MediaInfo shows it as having an 8 channel DTS audio stream). I thought I had 7.1 DTS-HDMA audio in it (DTS-HDMA lights came on on the receiver), but XBMC showed it as only outputting 5.1. So is there something I'm missing with this tutorial to get this working properly?

I have the same issue with xbmc. DTS-HDMA 7.1 displays as only 5.1 within xbmc but my receiver displays and pushes out a 7.1 stream. I think it's an issue with DTS-HDMA 7.1 media flagging within xbmc because TrueHD 7.1 shows fine with proper media flags and all.

I'm thinking that this is the issue. It appears that under all settings (I tried various channel setups), XBMC will erroneously report that the stream is 5.1 rather than the 7.1 it is actually putting out. I verified this by playing a scene in the movie I was watching that was a high action scene, and would make use of all 8 speakers. Sure enough the back speakers were outputting sound.

Under all settings in XBMC, from 2.0 to 7.1, the DTS-HDMA lights popped on on my AVR. So I suppose this might be an issue with this not being a final release of the HD audio code for XBMC?

Either way, I'm glad I figured it out.
