PCI Subsystem ID 1af4:1100 is qemu/kvm (not only Intel HDA, most other
emulated pci devices have it too). Complete entry:

00:04.0 0403: 8086:2668 (rev 01)
        Subsystem: 1af4:1100
        Physical Slot: 4
        Flags: bus master, fast devsel, latency 0, IRQ 11
        Memory at e2030000 (32-bit, non-prefetchable) [size=16K]
        Kernel driver in use: HDA Intel
        Kernel modules: snd-hda-intel

cheers,
  Gerd
