Windows 10: Dolby Atmos option not appearing in spatial sound

Hi guys, I have a new soundbar with Dolby Atmos and connected it to my TV and PC. I can open it in the Access App and also test the audio but when it tells me to change spatial sound, i cannot select Dolby Atmos.I know that there are a lot of topics here but I already tried all things written there as possible solution Windows 11 update Delete drivers Exclusive Mode off and on Compatibility mode

Dolby Atmos

I checked this line:

5. Look for Dolby Atmos to make sure that it is properly installed.

and i have list with my two audio cards :

1. onboard - Realtek High Definition audio

and

2. dedicated Asus xonar DG audio device.

When selecting option 1. i have spatial sound dolby atmos option, but when selecting option 2, i have listed only "none" under spatial sound.

I can confirm that i had spatial sound on previous win10 build

For this part:

• From the Start menu, type in Device Manager, then Enter.
• Then click the Sound, video and game controllers driver.
• Look for Dolby Atmos, then right click on it, then click Unintall.
• Once done, remove your Dolby Atmos device and restart you computer.

i dont have dolby atmos under sound, video and game controllers

 

Dolby Atmos for headphones not selectable in spatial sound

I just using standard pair of 3.5mm headphones connected to the computer. Dolby Atmos for headphones is advertised to work with any headphone. This has worked previously for me. I just no longer have the option to select Dolby Atmos for headphones under
spatial sound.

 

Dolby Atmos for headphones not selectable in spatial sound

I have the same issue with the Dolby Atmos Spatial Sound option removed all of a sudden. I have used it for months and not long after upgrading to 1903 the option has disappeared. Every other sound enhancer available works for me, just not Atmos...
