@alturismo Create "/etc/modprobe.d/snd-hda-intel.conf" inside the VM with the following content and restart the VM.

options snd-hda-intel enable_msi=1

Crackling sound should be gone with this.

Thank you! This fixed not only audio issue but also video playback (video was pausing in sync with audio at least while testing youtube).

 

Still getting weird screen artifacts on the top right of my primary and top left of my secondary monitor, any clue as to what that could be?

 

I've got ryzen 1600x, ASUS Prime B350-PLUS mb, GTX 1060 3GB (only GPU) passed through and running Ubuntu 19.04. In the Ubuntu software updater I've enable use of the nvidia-driver-418 as Nouveau was extremely unstable (although I haven't tested that with MSI enabled).

 

Please let me know if more info would be helpful!
