Audio Interface stutter / crackling on new OpenCore Ryzentosh system

Hi all.

First some context. I am a hackintosh noob, for the most part. I have had a successful hackintosh system in the past running Clover with Mojave, and that ran on a Gigabyte H87-HD3 motherboard + Intel 4670K CPU. I also used an audio interface - Komplete Audio 6 - which operated pretty much flawlessly during music production.

Recently, that motherboard gave out. So, for better or for worse, this is what my PC build is now:

CPU: AMD Ryzen 3200GMobo: Gigabyte Aorus B450 EliteRAM: Corsair Vengeance 2x8GB 3000MHzStorage: 2xSSD (Windows & macOS boot drives), 2xHDD (Windows & macOS storage)PSU: Corsair RM650

So, I got to work with OpenCore, setting up a fresh Mojave build. It was my first time using OpenCore so I following the guide on dortania.github as closely as I could, and by the end of it, everything booted up fine, but I noticed my audio interface had crackling / stuttering audio. AppleALC worked fine of course, but I need my interface for production.

I searched around for issues like this. Some people had it with other interfaces. I tried a few suggested fixes - like turning off Serial port (?) in BIOS, plugging it into different USB ports, sleeping the OS and waking it again, switching around the sample rate in Audio MIDI Setup etc. Still the same.

So I followed more of the OpenCore post-install guide, and successfully made a USB Map kext to properly set up my USB ports - but that hasn't made a difference either.

In the OpenCore Post-Install guide there is a brief section called 'Fixing USB Power', which provides an AML file. It didn't mention anything about AMD but I tried it for the heck of it & it didn't do anything.

Just to be 100% sure it's not a general issue with macOS and this interface, I tested it on a MacBook, & it worked flawlessly as it does on Windows.

I heard that hackintosh systems should not be relied on as your primary workstation, but this still has me bummed out, and I'm determined to try and find a solution if possible.

Any suggestions about what I could try? What the problem might be? I really appreciate any help. Thank you.
