Unable to get C602/x79) ALC662v2 working

[xayide]

I tried using SSDT and also the Lilu.kext and Applealc.kext. The dreaded ALC662v2 doesn't show up. I tried the long thread of Realtek https://www.tonymacx86.com/threads/applehda-realtek-audio-guide.234732/ but it doesn't explicitly say anything about C602/X79 more than I seems to not be natively supported. So I tried making dsdt-edit with AZAl to HDEF replace which from what I understand will not work, but I tried anyways. Anyone got a hint for me?

I got the HDMI / DP working using SSDT-1.aml after SSDT.aml for cpu. the SSDT-1.aml renames GPU from just "display@0" to GFX2 which is for MACPRO6,1 and then injects HDAU for HDMI/DP audio which works. (except HDMI doesn't work at all computer locks up but DP does, even sleep)

No dsdt/onboard audio support (AZAL, HDEF, etc.). Install ssdt_hdef-1-no_ioreg:hdef.zip, restart
If no audio, see No Audio Devices - AppleHDA Realtek Audio/Post #1/Problem Reporting.
Post to thread linked with requested files attached.

Thanks for helping. I tried it but no dice I saw it is actually there (HDEF) but not in Audio prefs. I posted in the other thread.
