Starship/Matisse HD Audio Controller Problem (Realtek® S1220A)

[alexthenumber1]

I recently completed a Ryzen build for my new unraid server.

 

The System-Specs are:

Mainboard: Asus Pro WS X570-ACE

Audio Controller: Realtek® S1220A

CPU: AMD Ryzen 9 3950X

 

So i am able to pass through my GPU and other devices to the Windows 10 VM. The Audio Controller also works fine for several times, but often unfortunately the VM crashes and as soon as i restart it the controller wont work 100%. 

 

I can use my microphone as normaly and the front audio panel inputs too, but the rear audio output wont play any sound. In the Realtek driver settings i can see that the audio devices is plugged in and also that theres sound beeing played but i cant hear anything beeing played.

 

It seems to be random because sometimes it works without a problem but then sometimes theres nothing i can do to get it to work.

i tried to reinstall driver, restart the vm and the computer but nothing changes.

 

 

Additional information:

The Audio Controller has its own IOMMU-Group

 

 

 

 

This is my VM-File:
