Audio device in VM without audio device in configuration

[arnoproxmox]

Hi,

After creating a VM (see image) there is an audio device in the Debian VM.
No audio device in configuration and no passthrough.

Please explain.

(pveversion pve-manager/8.3.2/3e76eec21c4a14a7 (running kernel: 6.8.12-5-pve)
Packages up to date.
Debian 12 Host and VM.

I believe the original Q35 motherboards had an audio device, but AFAIK it's not functional. I tend to bind it to pci_stub to hide it from audio software.

It's not specific to Proxmox or any kind of VM. It's because of QEMU/KVM: https://wiki.qemu.org/Features/Q35. Maybe Proxmox could hide/remove it?
