I strongly suspect the VIA chipset has broken MSI support and probably needs a
quirk to disable it.  I don't see any MSIs getting triggered:

  64:          0          0   PCI-MSI-edge      aerdrv, PCIe PME, pciehp
  65:          0          0   PCI-MSI-edge      aerdrv, PCIe PME, pciehp
  66:          0          0   PCI-MSI-edge      aerdrv, PCIe PME
  67:          0          0   PCI-MSI-edge      aerdrv, PCIe PME
  68:          0          0   PCI-MSI-edge      snd_hda_intel
  69:          0          0   PCI-MSI-edge      snd_hda_intel

Does sound work ok?
