5.1 Audio on XBox Series X

I have the same problem but i cant even enable 5.1 audio i can enable 5.1 audio but if i select HDMI on video output, instead of automatic. But that only allows me to select 1080p resolution, not 4k. So i can only use 4k or 5.1 audio on Xbox One X

Hello sizzle,

Thank you for contacting Forum support!

Dolby Atmos support on Xbox One and Xbox One S, with this feature it enables all Xbox consoles to pass Blu-ray audio data untouched to a user’s audio equipment, allowing your audio receiver or other audio device to produce a high
quality, immersive sound experience.

Audio Components with Xbox one X:

DTS: 5.1

DOLBY Digital 5.1, TrueHD with Atmos

PCM

Hope this helps.

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 had the same issue and figured it out. My LG TV had the HDMI port I was using for my Xbox series X set to an audio input format of PCM (like my PS5 in the next HDMI slot). I changed it from PCM to bitstream and on the Xbox settings the Dolby Atmos and 5.1/7.1 options returned.
