This is the second xbox one that the voice tracks disappear in games AND movies. Support told me first xbox had bad hdmi and optical port but I think that was a load of crap as the second is doing the same thing. My reciever supports dts and dts hd and so did the blu ray I just watched yet the voices dropped out after about 20 minutes. Netflix and Hulu do the same thing. Both optical and hdmi are set correctly. Frankly this is getting a bit irritating spending $500 on a console that wont play movies or games in surround sound.
