Windows 10: Spatial Audio Dolby Atmos No Sound in games but works in Apps like Dolby Access & Netflix App

Everything was working I haven't made and system changes apart from windows updates not sure which ones. and then the atmos just stopped working for no reason. Issue noticed in the last week or so. I am using Sonos HDMI set up so the phone app always tells me what signal I'm getting. Before playing games it always showed as Dolby Atmos. Now if I select Dobly Atmos from spatial audio / format all I get is silence but I can see the volume bar active just no sound. I can now only get sound if I switch off spatial audio and app shows I'm now using Stereo signal and I can clearly tell the differenc

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.

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 for headphones not selectable in spatial sound

Thanks all for assisting, I now have the option for Dolby Atmos for headphones. This was fixed by following instruction from Dolby Atmos support, completely terminating the Dolby Access process via the task manager is what
fixed my issue. Below is the instructions sent by Doby Atmos support for anyone with the same issue to try.

Code:

Hi there!

Thank you for reaching back out to Dolby Atmos support! 

In our testing we have found that reinstalling Dolby Access and completely restarting your device should restore Dolby Atmos.

If not, please try completely terminating the Dolby Access process via the task manager. Please note, you need to keep Dolby Access open when doing this so that is shows in the apps list. This method will not work if simply closing the app normally using the
 X button. To accomplish this:

1. Open Windows task manager: Right-click in your system taskbar and choose task manager or choose the option after pressing ctrl-alt-del.

2. Find Dolby Access in the apps list, select it, then choose the End task button. This should end the Access app and also associated background processes.

3. Double-check in the Background processes list that "runtime broker" is also ended. If listed, please end this as well. Now, please launch your Dolby Access application and configure your sound settings from directly within Dolby Access.

If this does not resolve your issue, right click the volume icon in the system tray and select 'playback devices.' Then, right click your audio device and choose 'properties.' Finally, find the Enhancements tab and uncheck 'Disable all enhancements.'

Next, please ensure your audio isn't set to Mono or one channel sound. In Windows, search for your Settings, and choose Ease of Access. In the Audio section, you will see an option to turn on MONO. Make sure this is turned OFF. Once this is off, enter your
 audio settings to configure Dolby Atmos again. 

If this is not checked, then please navigate to your ‘Apps & Features’ folder on your PC via the Cortana search bar. Within Apps & Features, ensure there are folders for both ‘Dolby Access’ and ‘Dolby Atmos for Headphones’. It is very important that you have
 both of these files as these are needed for you to be able to use Dolby Atmos for Headphones on your device.

If you see both of these files, click on ‘Dolby Atmos for Headphones’ and uninstall this from your PC. Once complete, open the Dolby Access application and reinstall Dolby Atmos for Headphones from there.

If you only see ‘Dolby Access,' please click on it and select 'Advanced Options,' then 'Reset.' Once complete, open the Dolby Access application and install Dolby Atmos for Headphones from there.

We appreciate your patience, and hope you have a wonderful day!
