XBox One Audio Question

[ouchmyfacehurts]

So I just got one of these. I have three other blu ray players including a PS3 and none of them have the following problem... The audio isn't being encoded by my 5.1 receiver. It just comes through as PCM. Generally, I would think when the thing is set to bitstream, it would send it out as PCM to the receiver to decode the DTSHD, Dolby TrueHD, etc. but it does not. Bitstream actually seems to downgrade the audio to DTS or Dolby Digital.

Add to that, that unless it is a bluray, a game, or netflix, there is no way to get surround sound. The only way to kind of fudge the surround sound, is to go in to the audio preferences and change it from 5.1 to stereo. Then it lets my receive use Pro Logic II to mix to 5.1, which is fine for movies but a definite step down for something like Fallout 4.

Is there a way to unbastardize these audio settings?
