Intel Chipsets have Special Audio Bus - Smart Sound Tech Bus. And Special Drivers - Intel SST and - Intel OED Bus Drivers. Alan Make Drivers for this.Worth a shot I guess...
Unpack The original installler, Replace attached HDX.inf with the original and run setup (signature verification disabled).
The AAF Bus, should not - according to my understanding, represent a compatibility issue in this scenario as Alan left the door wide open even for unknown HDAUDIO bus drivers to get picked up by his driver. And remember... this is ONLY the bus... Which is 'equivilent' to the standard Microsoft High Definition Audio Bus Driver.
It's the specific audio interface/chipset that requires the extra attention.
Thanks
