Windows 10: Installing Dolby Access causes HDMI audio issues

I've got RTX 3090 FE, LG CX TV, and HW-Q80r. When I install Dolby Access all my audio outputs when selecting said HDMI have issues. Stereo and 5.1 options don't work at all. 7.1 pops in and out and Dolby Atmos will cut off when closing audio files or video files. I have eARC, passthrough, and bitstream selected on my TV and the soundbar is connected correctly. I have no issues with soundbar when connecting straight through it from my PC, but I lose G-Sync and HDR. Uninstalling Dolby Access doesn't fix the other audio outputs either. I've reproduced this 4 times now from clean installs of Windows 10, so i'm really just trying to find out what's causing it. It's either Windows 10, the LG CX, or the RTX 3090 HD Audio Driver. Any help would be so much appreciated. I've also reached out to LG already on this issue.

Dolby Advanced Audio and Dolby Digital Plus Advanced Audio

Hi Polaris,

We appreciate you for being a part of Windows 10.

I understand that you are able to use the Dolby Digital plus Advanced Audio and not able to use the Dolby Advanced Audio.

As you get the error “Unable to start the Dolby Audio Driver. Restart the computer or reinstall the driver”, this error might occur if the driver is not installed properly or it is not up to date. I suggest you install the
Dolby audio drivers. Refer to the following article to update all the drivers available in Windows 10.

How to: Install and Update drivers in Windows
10



As the both Dolby Digital plus Advanced Audio and Dolby Advanced Audio are listed under the programs and features, you may uninstall the Dolby Advanced Audio through Programs and features.

• 
  Press Windows + X keys on the keyboard, select
  Programs and features.
  
• 
  Right click on the Dolby Advanced Audio and click on
  Uninstall.
  
• 
  Click on OK if any window prompts.
  

After uninstalling the Dolby Advanced Audio, you may reinstall it again through the setup file (If you have) or from the Dolby support.
I suggest you to refer to the suggestions provided by

Dolby Advanced Audio drivers.

Dolby Advanced Audio and Dolby Digital Plus Advanced Audio

I upgraded to Windows 10. On the Control Panel, both Dolby Advanced Audio and Dolby Digital Plus Advanced Audio are listed.

Neither one is listed in Device Manager. When I click on Dolby Advanced Audio, It says, "Unable to start the Dolby Audio Driver. Restart the computer or reinstall the driver". Clicking on Dolby Digital Plus Advanced Audio the app opens. Do I really need both?
Both are listed on Programs and Features.
