Audio stuttering DP output only when focusing video on driver 530.41.03

Hi guys,
I’m trying to virtualize Arch Linux in Proxmox with GPU passthrough (Nvidia 1060) but audio is weird.

If I have firefox with a video on focus, the audio will stutter, but if I hide the window it will kind of play normally (after a while it will still stutter).

It will also stutter if I move the mouse around or press some keys on the keyboard.

I’ve already enabled enable_msi option but it doesn’t seem to work.

cat /sys/module/snd_hda_intel/parameters/enable_msi returns 1

I’ve used archinstall script to install my minimal setup with KDE configured

I don’t think that the issue could be Proxmox because I also tried with Fedora and audio works till I install nvidia drivers using this guide Howto/NVIDIA - RPM Fusion, whereas with nouveau I don’t have any kind of issue.

Any suggestion?
