No sound from auvia (VIA VT8237)

Hello everybody,

The auvia sound driver seems not to work properly on a
VIA EPIA-CN10000EG motherboard. (When playing audio files with any of
ogg123, mpg321, or audioplay, the command gets stuck and I don't get
any output.) I'm using a netbsd-4-0-RC1 GENERIC kernel, see attached
dmesg.

I tried

   options        PCI_ADDR_FIXUP          # fixup PCI I/O addresses
   options        PCI_BUS_FIXUP           # fixup PCI bus numbering
   options        PCI_INTR_FIXUP          # fixup PCI interrupt routing

which didn't help.

What does help is using the GENERIC.NOACPI kernel; sound output is
fine with that kernel.

Is there a way to have both ACPI and the auvia driver work?

Cheers,
  Christoph
