Correct me if i am wrong but according to some sources (i.e. wiki) DTS HDMA does not actually contain 7.1 track.
It contain "core" track for backward compatibility (which is lossy) and "residual" track that contain information necessary to build lossless HDMA audio from "core" track.
I assume (cannot verify it) "core" track will be 5.1 (since there were no 7.1 in old days). As there is no actual 7.1 track in DTS HDMA, XBMC might be picking up only "core" track.
This is unlike Dolby TrueHD, which actually have 7.1 lossless track. Thats probably why XBMC reports correctly 7.1 for TrueHD
