Hi,
Agreed. If we can know the virtual device for KVM in a better way
(e.g. any specific PCI SSID or such), we can narrow the condition more
safely.
PCI Subsystem ID 1af4:1100 is qemu/kvm (not only Intel HDA, most other
emulated pci devices have it too). Complete entry:

Hi,
We discuss Intel ICH/AC'97 (snd-intel8x0) here, but I hope that PCI SSID
is same.
Hmm, it's not, the ac97 emulation doesn't use the default qemu subsystem
id for some reason. Here is the entry:
