USB Audio passthrough require proxmox reboot to work.

[konst24]

I passed through USB device to windows 11VM and it worked fine. After rebooting the VM, indicators on audio panel show presence of signal, but no sound could be heard. After experimenting, it has become apparent that audio would work only after complete proxmox reboot and only 1st time VM is started. Audio does not work if I reboot the VM or under any other circumstances.

I did try to pass pci controller responsible for USB to VM: the audio works fine in this case, but VM gets ALL usb ports, which is not an option for me.

Built-in Audio to MB -> ALC4080
0b05:1a52 - the USB address
/dev/bus/usb/001/002 - USB Bus and device

Host: Proxmox 8.1.3.
Guest VM win11 23h2 config is on image.

I am a beginner in this area and wanted to ask if there is any command in proxmox to simulate reboot of the proxmox for audio USB port.
