Audio work's out of the box now with all vanilla kext's.

When working with the ITK, and customizing AMI/DMI with Framework toolkit, you can change audio sig's from AZAL to HDEF. This isn't possible with using the DSDT.aml way that is refered to above.

I have a completely custom BIOS, with a correctly filled out SMBIOS. I also have achieved native HDEF sound with changing AZAL to HDEF in my ITK. Video, I am looking into and it isn't looking good. We will alway's have artifact's using Intel GMA950 without using a UGA driver on boot, which you need real EFI for!

If you have an newer Intel board, I can prolly help you greatly.
