Hi,
I also have 2.0.6 and sound works perfectly as it should. Of course that is true only for integrated Himedia Player. Sound settings should all be set to RAW for HDMI and I got working AC3, TrueHD, Atmos, DTS, DTS-HD and DTS-X.
What player are you using? Also sometimes it happens, at least on my Denon, that you should press Auto audio mode on AVR's remote to detect correct sound.
BTW, you're saying DTS-HD-HR. What is HR?
