Hey everyone. I'm having issues with my Komplete Audio 6 audio interface on my OpenCore 0.6.0 Ryzen 3200G Mojave build.
Description of the issue:
The audio interface's output is crackly and stutters all the time, but not always with the same intensity. Sometimes there are only a few stutters per minute, but most of the time it's constant crackling.
Some things to get out of the way first:
Thank you

Some things to get out of the way first:
- My system audio is working fine with the AppleALC kext. The issue lies with my USB powered audio interface.
- The interface works fine on my Windows 10 installation, and it works fine when plugged into a genuine MacBook Pro, so it's not an issue with the interface itself.
- The interface used to work flawlessly on my old hackintosh build, which ran Mojave on Clover with an Intel 4670k CPU and Gigabyte H87-HD3 motherboard. That motherboard gave out recently, so for better or for worse I chose to make a Ryzen build (specs are in my signature).
- ACPI contains SSDT-EC-USBX.aml (made by me - renames XHC1 to SHCI).
- Drivers contains HfsPlus and OpenRuntime.
- Kexts contains AppleALC, Lilu, RealtekRTL8111, USB-Map (made by me), VirtualSMC and WhateverGreen.
- config.plist is set up following the basic OpenCore guide for Ryzen + adjustments for FileVault.
- boot-args: keepsyms=1 debug=0x100 alcid=1 npci=0x2000
- I tried manual USB mapping, following the Dortania OpenCore guide. I took the 'long route' all the way through - making my own SSDT-EC-USBX and USB Map kext. It was a success, but made no difference to my audio issue.
- I tried plugging the interface into different USB ports. The crackling kind of 'switched' to random levels of intensity as I went through each port, but all had the issue.
- I tried using a powered USB hub.
- I tried turning off 'serial port' (?) in my BIOS settings.
- I tried GenericUSBXHCI.kext, XLNCUSBFix.kext and AMDTscSync.kext.
- The SMBIOS I am using is iMac14,2 - I was recommended that one on the OpenCore guide due to my Nvidia card. However I have also tried the iMacPro1,1 and the issue is still there. I could try others.
- I tried sleeping the system and waking it again.
- There is a brief section in the OpenCore post-install guide 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.
- I tried changing the sample rate of the interface in Audio MIDI Setup to 44.1KHz and 48KHz.
- I tried installing old Komplete Audio 6 OS X drivers from the Native Instruments website, but the installation fails.
- I tried booting with Clover with roughly equivalent settings - same.
- I saw a reddit post where someone suggested adjusting the voltages of my USB ports in the BIOS settings, but I don't think my BIOS has such settings.
- I saw someone suggest the issue is that the CPU is one of the Ryzen 'G' series, which has known issues with audio, but most of the people I saw with those audio issues were having system audio issues, and one of the solutions people were giving was to get an audio interface like I already have. So I'm very unclear on that. If it's the 3200G, I could try to return it and get a 3100 (or something else?) but I would have to act soon.
Thank you
