Surround Sound problems.

I have had my Xbox One since launch. I've noticed recently that I am not getting 7.1 sound out of my Xbox One like I used to. It sounds like everything is being downgraded to 5.1 or stereo. Is anyone else having a similar issue. I have been through all of
the audio settings on the xbox one. It is set to 7.1 uncompressed. Any thoughts would be helpful. My av receiver seems to be setup correctly as well.

I have a Sony TV led hdtv, and Denon Avr-x2000 receiver.

Surround sound problems

Noticed some issues recently regarding surround while using the xbox. Setup is dish 722k to xbox one to pioneer vsk522k receiver to tv. When using the xbox to play a DVD or play games, front volume is low and voices switch between center channel and
right and left channels and when it's thru center channel its even lower. sound effects and music sound fine. I noticed this lately when I started playing wolfenstein, voices from the front are super low, back is much louder. Thought it was just the game
but recently put in a DVD and its similar issues. Sound from the dish receiver sounds just fine and a htpc connected to another input on the surround receiver sounds fine so it seems isolated to the xbox one. Any ideas? I've tried messing with the audio
settings with nothing fixing it.

 

Surround Sound Problems

I am not sure how long I have had my current problem, but I began realizing that my center speaker in my surround sound system is outputting no sound at all when hooked up to my Xbox one. The Xbox is connected with HDMI to the receiver and the receiver is
connected to a projector, but I have also tried connecting with a fiber optic cable and have experienced the same problem. My blu-ray player connected to the same receiver by HDMI has no issues with the center speaker not working, so I believe it to be either
an Xbox issue or a configuration I may have overlooked. My receiver is a Sony STR-DH520 and the speakers are all Onkyo. I can get the center speaker to have audio from the Xbox one, but only when the output is set to stereo, which obviously destroys the point
of surround sound. Even when configuring the Kinect with the surround sound it doesn't play the musical tone to test the speaker level from the center speaker. I am happy to try anything that might fix the issue. I entertained the idea that there might be
a problem with the cables themselves, but found it unlikely that both the HDMI and optical cable would have the exact same issue.

This is the link to my receiver's manual. Currently the display shows LPCM 48 kHz when connected via HDMI audio, regardless of my chosen surround sound field.
