Xbox One surround sound issue
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.
