[OC 0.6] Can't get AppleALC audio working on ALC280 [Dell T5810 X99, Haswell-E]

I've tried every single available layout-ID for the ALC280 chip with AppleALC.kext and none are making the system see the audio card whatsover. I've tried alcid= 3, 4, 11, 13, 15, 21, and 27, each several times. VoodooHDA brings up four seperate HDMI audio outputs but no analog.

I've tried three different versions of AppleALC, 1.3.4, 1.5.0, and 1.5.1. 1.5.1 doesn't load at all, the other two load but don't do anything.

- Dell T5810 workstation with X99 chipset, Haswell-E Xeon E5

-ALC3220/280 audio

-10.14.6 Mojave

-OpenCore 0.6

Any ideas? Thanks!
