Audio stuttering with AppleALC and Voodoo AMD

5800x, 32gb 3200 CL18 Corsair Venagnce, B450 MSI Pro Carbon AC, ASUS GTX 780 Direct, 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 mojave or HighSierra. (As well as a UEFI GPU?)

What I've tried:[ HD 5850, HD 5770, & R9 290 (both need UEFI to boot with OC 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 OC config

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

Haven't tried: [

RX 590 Polaris (however this machine needs NVIDIA for video apps) ] I'm using OC version 0.6.4 and version 0.7.1 won't boot even with SecureBootModel off.

Are there any patches/SSDT for fixing USB audio for Mojave/HighSierra?

Thank you
