I've successfully set up GPU pass through with KVM (with Proxmox), but I'm having some annoying issues with audio in my Windows 10 VM. After a lot of experimentation, I found that passing through my motherboard's onboard audio worked best. However, audio still crackles and distorts whenever there is significant disk or network I/O. Oddly enough, game audio works fine, but Youtube and other streaming services have issues when, say, downloading a Steam game in the background. I'm using the virtio drivers for disk and network, which should reduce the I/O load but I'm still having this annoying audio distortion. Any tips? BTW, audio works great under ESXi. I'm just more familiar with Linux, and prefer having a graphical desktop for the host.
