From Amazon Music using the app via my Xbox-X.
Yeah, don’t. Amazon Music and Apple Music do not support Dolby Atmos output on the XBOX Series X/S.
Here’s what happens. Both services only support two channel output on XBOX Series X/S. I’m not sure it’s even their lossless versions and could be AAC.
When you run the XBOX Series X/S in “Dolby Atmos for Home Theater” after downloading the Dolby Access app, all non Atmos signals will be up mixed.
Some receivers will display the incoming signal as Dolby Atmos. My Onkyo knows better and displays the signal as Dolby Surround.
But, isn’t Dolby Surround an up mixer and not a signal codec? Yes, but the signal has already been up mixed at the source.
So, I will have Dolby Surround as the incoming signal display and Dolby Surround as the selected sound mode when I select it.
So, when playing tracks from Amazon Music or Apple Music, the track will start in two channel PCM and then suddenly switch to Dolby but not deliver any audio to anything but the fronts and sub.
Microsoft needs its Dolby license revoked. They have really f#%ked it up with the up mixer. Dolby Atmos output works for games and videos with actual Dolby Atmos tracks but Amazon Music and Apple Music do not support Dolby Atmos on the XBOX Series X/S.
I purchased an Amazon Fire TV Cube 3rd Generation just a few days ago. Lovin’ it. It supports hi-res and Dolby Atmos playback from Amazon Music. Apple Music Dolby Atmos tracks are only supported on the Apple TV 4K.
