If only it were that easy.
I appreciate the input. The one thing that I didn't have set like that was the "Best Match" option, but I had that on "Optimized" that I believe does the same thing but that it won't switch after the file starts playing. But, I tried Best Match and still don't get 7.1.
Maybe my files don't have 7.1 even though I choose to extract that track, but the audio track when I pulled it up on XBMC says "7.1" in it...but it also says "5.1" on the same line.
