Ryzentosh Audio worked fine until adding GTX 780

5800x, 32gb 3200 CL18 Corsair Venagnce, B450 MSI Pro Carbon AC, ASUS GTX 780 Direct CU II, RM 650x

Hello, I made this build as a video workststion, which requires NVIDIA CUDA, and for audio production. The last non-ti NVIDIA GPU that's supposed to work fully with any MacOS. The audio MacOS side needs Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave or HighSierra. (As well as a UEFI GPU?)

What I've tried:[ -OpenCore 0.7, 0.7.1, 0.6.4 won't boot. Stuck at end randomseed and tried MinDate and one below to -1 and 0. Secure bootModel off and Default.

-Added AMD Patches with 8 core hexidecimal, in three replace fields.

-Tried OpenCore 0.5.7 and 0.5.8

-Changed platforminfo (iMacPro1,1 for polaris) I copied config and changed to iMac14,2(for Kepler and Maxwell)

-HD 5850, HD 5770, & R9 290 (both need UEFI to boot with OpenCore and FAKE ID guide for R9 doesn't work [on several different machines])

-NI and Scarlett audio interfaces and internal, all stutter like buffering digital radio in tunnel

-10.13 and 10.14

-Internal audio

-VoodoHDA Kext and patched in OpenCore config

-Generating SSDT-HPET from windows with dumped DSDT and patched in OpenCore config ]

Haven't tried: [

-RX 590 Polaris (however this machine needs NVIDIA for video apps) ] The last build with the same motherboard, using OpenCore version 0.5.7 worked before swapping RX Polaris with Maxwell GTX 780. version 0.7.1 won't boot even with SecureBootModel off.

Are there any patches/SSDT for fixing USB audio for Success' href='/2020/12/install-macos-mojave-on-supported-pc.html'>Mojave/HighSierra?

Let me know if you want to know the kexts I used.

Thank you
