Hyper-V GPU Passthrough - No Audio

[Kreeze]

I was able to get 2x GPUs passed through to Hyper-V VMs. I will use 1 GPU for video streaming on a TV and 1 GPU for Steam streaming headless. I am currently troubleshooting the former.

 

Plugging the GPU into the TV via HDMI displays video, however the audio is not passed through. The audio device (NVIDIA High Definition Audio) is still attached to the hypervisor (Windows Server 2022) and I can choose the TV as an output from the actual server instead of the VM. I do not know how to pass a sound controller to my VM. I used this lovely guide to get this far: https://www.techtarget.com/searchvirtualdesktop/tip/Running-GPU-passthrough-for-a-virtual-desktop-with-Hyper-V#:~:text=GPU passthrough setup with Hyper-V&text=The easiest way to do,command from the shortcut menu.

 

What am I missing here? Can I even use DDA to pass an audio controller, or do I need to do it in some other way?

I ended up switching from Windows Server to Unraid. Unraid gives the ability to choose a soundcard for passthrough which I was not able to find in Hyper-V. There's a nice video by Spaceinvader One explaining how to do it
