Dolby Atmos using HDMI audio and a 3.5mm chat headset switch to stereo

The Xbox audio settings I have available are as follows:

HDMI audio:

* Stereo Uncompressed

* Dolby Digital

* Dolby Atmos for Home Theater

Headset Format:

* Stereo Uncompressed

* Windows Sonic for Headphones

* Dolby Atmos for Headphones

* DTS Headphone:X

Tried all of them. Nothing helped.

We could surely try to help you better if you provided more information to pinpoint the issue better.

What hardware are you using to play audio? How is it connected?

Are you playing audio through your TV via HDMI? Or are you using a soundbar or AV Receiver? Are they connected via HDMI as well, or are you using the optical cable?

Or are you using a headset and getting sound through the 3.5mm jack of your controller? Or is it a wireless headset?

What audio settings are you using? Stereo, 5.1 surround, Dolby Atmos, Windows Sonic?

Go to xbox settings, Choose "General", Set "speaker audio" to HDMI Bitstream out, then set " bitstream format" to Dolby Atmos for home theater. This will allow all games and apps that support dolby atmos to use those nice surround sound speakers. If you
get an error when choosing dolby atmos, you may need to make sure your hdmi from the xbox goes to the audio receiver directly with the audio reciever sending hdmi to the tv.

You may have to adjust settings on your audio receiver or tv.

You can also setup dolby atmos for a stereo headset pugged into your controller and have surround sound that way, nice for late nights when others are sleeping.

Let me know if this helped

Thanks for that suggestion. It seems to still only offer up Multichannel out, no Atmos yet. I switched HDMI Audio to Stereo Compressed, then in Video Fidelity set Overrised to HDMI, then set resolution to 1080p and refresh to 60Hz, and made sure colour
depth was left at 24-bits as per the suggestion above. Switched the HDMI Audio back to Bitstream and the format back to Dolby Atmos for home theatre, but still no luck on outputting an Atmos signal.

Yeah, I tried all of that, nothing works. Switching between audio formats makes it glitch and waiting a second resets it but it still only works on stereo and 5.1 but the Atmos works FINE on movies, Dolby App etc. Atmos works, just not in games. Its clearly
an Xbox issue.

Troubleshoot settings

In-game audio issues when using Dolby Atmos:

If you experience audio problems when you’re using Dolby Atmos, try turning it off:

1. Press the Xbox button to open the guide and select System >
   Settings.
2. Select Display & sound, then from the headset audio options, select
   Stereo Uncompressed.

Frozen speaker settings after you disconnect a Windows Sonic or Dolby Atmos headset:

In most cases, disconnecting or turning off a headset/device configured for spatial audio (Windows Sonic or Dolby Atmos) will return the speakers to their previous audio settings. However, certain hardware—such as wireless headsets using an intelligent transceiver
plugged into USB—might still show the headset is connected even after it’s disconnected or turned off.

Unplug the headset or the headset component attached to the Xbox. This should immediately return the speakers to their previous configuration without changing the headset or speaker audio settings. Plugging the headset or the headset component back in should
restore the headset format you’ve chosen.

If you’re still having problems switching between speakers and headset on Xbox One, check the headset/speakers manufacturer’s website for more info.
