Windows 10: Dolby Digital not showing up in Shared Mode

So, i'm trying to connect my AV reciever to my Windows 11 PC via S/PDIF. My reciever only works with 5.1 sound, if I use Dolby Digital. It works if I use the Test button for Dolby Digital.However, every other App doesn't work with 5.1 Dolby Digital.I've read, that I should select Dolby Digital as my Default Format, But it does not show up in the list.Windows Troubleshoot didn't solve the problem.Is this a Hardware problem?I am using Windows 11 Pro, 22H2, 22621.1105Hardware I'm using:Motherboard ASUS PRIME X570-PROReciever YAMAHA RX-V396RDSCPU Ryzen 7 3700XGPU RTX 2060S

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.

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.

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.
