Issues with channels playing (xbox and Marantz 8802a) Atmos or All Channel stereo


New Member

I have 2 issues that I have never resolved. I'm running 7.4.2 right now my Marantz amp assign is set to "atmos" with the proper configuration:

(I had the same issue when I was only running 7.2)

1) My Xbox One S still wont play the 2 rear channels when listening to music in Atmos
a) Xbox is set to Atmos Bitstream
b) Marantz is set to sound mode Atmos
c) Marantz amp assign set to 7.4.2 "Atmos"

2) My Marantz also does not play the surround side channels when I play sound mode "all channel stereo" and unlike atmos does play the rear channels. All the other 9 channels play sound fine. I've never understood this and aftr years of looking, still have not found an answer.

When I play Atmos movies, it plays out of all speakers fine.
