Cool stuff. I've never looked at PCI IOMMU traces before.

I don't see anything obvious when looking at those traces though, so we're probably looking at some type of chipset bug here.

I guess we're down to trial and error then? I e, try random changes to stuff that win7 does but we don't (or the other way around), and see if it helps?

E g, try don't enable unsol before probing (win 7 does not do that), or don't write 0xff to STATETS, etc...and see if anything of that makes STATETS detect the codec.
