Home Theater: No rear channel sound on Xbox One Optical Output

Hi - I've got the following connection:

DirecTV Genie >> Xbox One >> TV via HDMI

Then I've got an optical out from the Xbox One direct to a Denon AVR 2311 receiver.

I've got the Xbox One set to Optical Audio Bitstream Dolby Digital but when I watch anything on DirecTV the rear channel surrounds are silent.

Am I missing something? Or does Xbox One not output full 5.1 over Optical? If yes, what's the point of the Dolby and DTS options?

Will I get better results if I plug the Xbox into the receiver via HDMI?

thanks

:)

 

Xbox one surround sound issues.

Also I tried the hdmi bitstream mode with both Dolby options,however this doesn't seem to output any sound.

I can't connect my Xbox one directly to the spdif on the home theater,since I don't own a rca to optical toslink active adapter.

 

Optical audio out option 5.1 compressed

I have a home theater system with optical input and not the 5.1 already compressed as option informs the support site. On my system has only esterio options and uncompressed bitstream output. In the bitstream options are not presenting the sound in the center
box of the home theater
