Xbox music 5.1?

No, the Xbox One S does not simulate ATMOS from a 5.1 source.

However, since the Xbox One can run multiple sound applications at any given time (for example you run an Atmos enabled game, while having a music app running in the background), the console will ALWAYS output an ATMOS signal to your receiver, since the
game sound is in spatial surround.

Into that ATMOS spatial surround sound track, the stereo music track will be mixed in. But since the music track does not have surround or height information in it's stereo signal, you won't get the music in ATMOS spatial surround, even if your receiver
shows ATMOS coming in.

If you watch a 5.1 video in VUDU, the Xbox will distribute the 5.1 sound information to the front, center, back surround and subwoofer channels for the ATMOS signal, and your ceiling speakers for example won't get sound.

So even if your receiver shows ATMOS, and you have twenty speakers mounted in your home cinema, only the standard 5.1 speakers will produce sound, if you watch a 5.1 sound source.

Hi Darkstar,

The Xbox is working 100% as it should be. If the Xbox source signal is 5.1 i.e a game, then the audio stream to the receiver is 5.1 and the receiver will output 5.1 audio to the speakers. However if the Xbox audio source signal is 2.0 i.e music, then the
stream to the receiver is 2.0 and the receiver will not magically output 5.1 audio to the speakers.

This situation will happen for HDMI or optical using DTS or Dolby decoding etc. The Xbox will not simulate 2.0 up to 5.1. You will need to use one of the surround effects (simulation) on your receiver to scale the 2.0 audio to 5.1 audio. Sorry its not what
you want to hear, but this is how it works

I bet it's not surround, but Stereo Signal on your rear boxes as well. XBOX Music is a Stereo pcm Signal! Not a true 5.1 or 7.1 channels

I have a 5.1 dolby digital receiver/dvd player hooked to xbox one with an optical cable and to the tv with hdmi Xbox setting is set to bitstream out dolby digital and I get full 5.1 on games and blue ray works perfectly and menu sounds but any music or
video app or a dvd that has 5.1 audio won't work the music and video apps only give 2.1 and the dvd with 5.1 sounds so muffled I can't hear I have tried everything and all I can get is this or fake surround and I don't want fake surround if all the apps are
in 2.1 why wouldn't the Xbox be smart enough to mix the sound through all the channels of audio if the program only does 2.1

Its in 5.1 for me. I always turn off the music though. shouldnt make a difference but you never know.
