Windows 10: No Sound from Browsers with Dolby ATMOS

Over the past 2 days, I have noticed that enabling Dolby Atmos for Home Theatre option disables all audio from sites like Youtube, Netflix, etc on my browser - tested with Firefox, Edge, and Chrome. Audio is only heard if I change the option to 7.1 or below.


At the same time, audio via Atmos is working fine when playing movies via VLC, PowerDVD, Movies & TV app, while playing games, or even playing from the Dolby Access app. System auto detects the audio channels, and sends it out through the connected receiver, ie 5.1 plays as 5.1, and Atmos plays as 5.1.2.


The problem seems to have started on its own, as prior to 2 days ago everything was working fine. Tried reinstalling the Dolby Access app, and its still the same.


Setup - GTX 1080 -> AV Receiver -> TV

Windows 10 version 2004 Build 19041.685

GPU drivers are all up-to-date


Any help to fix this will be appreciated.

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:

• 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 won't install

I have downloaded the Dolby Access app through Windows Store, I have gone through the "getting Dolby Atmos" prompts through the app, I opted to go with the 30 day trial and it appeared to be installing Dolby while a loading spinner ran over the trial option.
Afterwards it prompted me to begin setup of Dolby Atmos by going to my device properties -> Spatial Sound -> Dolby Atmos...however the option "Dolby Atmos" is not there.

I figured maybe I just need to restart my computer to finish the install but even after restarting I still only see the option "off" under the Spatial Sound tab. There does not seem to be anyway to attempt to re-install the software as there is no program
listed for Dolby Atmos in my Programs list and the Dolby Access app seems to believe it is installed on my computer.

How can I go about fixing this issue?
