So far, I am able to pass through the GPU super easily to a Windows 11 VM, and have Intel driver software working for video just fine for high-end gaming.

However, I do not get the sound device showing up in Device manager - I am also passing it through to the VM too. So I have to use USB headset to get sound...

The Video and audio are in two different IOMMU groups... Any suggestions on what to do to resolve the sound issue?

Proxmox version: 8.3.0

Thanks!
 
Hi,

Sure thing - keep in mind I also have a VM using that Nvidia rtx3060 GPU too - sound and video work perfectly on that Win11 VM:
