Hello, I’m using a Windows 11 VM on Proxmox VE, and my audio keeps cutting out. I use GPU passthrough with my NVIDIA 2080 SUPER for gaming, but I don’t know where this issue is coming from. I’ve switched audio devices, but the issue persists. The audio cuts out for a few seconds, then comes back. I updated Windows to the latest version, uninstalled and reinstalled the USB Composite Device in Device Manager (using a USB to 3.5mm audio jack).
I don’t believe I experienced this issue before. This build uses a Librebooted Dell T1650 motherboard which uses SeaBIOS. Maybe I need to switch OVMF (UEFI) to SeaBIOS in the VM? Not sure what’s going on. This is a recently created VM, and the only things installed are my Steam games and nothing else. Any help is appreciated!
This was the issue! I enabled SMT and set my CPU cores on the VM from 4 to 8 cores and it fixed it. Thank you so much for the advice!
Awesome, glad that helped and thanks for the update!
