#Kext utility freezing Patch#

^perhaps these were the causes of my issues all along? There had been an additional patch that mirrored what I'd seen for High Sierra all USB patching that I had removed, but I've only just removed these. Thank you for any help / ideas you can offer!

In Catalina, I seem to be able to choose a different audio device then go back to my external interface to reset the driver and get sound back. On High Sierra, the crash was irrecoverable- opening sound in system prefs just froze up, and I have to reset the system to get audio back. My audio issues still have not been fixed, though. My USB ports now show up properly (though I've excluded my mobo's type-c port to meet the 15 port limit). I also disabled the 15 port patch which had been left on. I also learned that USBInjectAll hadn't been given a custom SSDT and so I made one, which I have included at the end of this post. The shikigva=4 & -rad4200 boot arguments weren't available in WhateverGreen so I didn't add any boot arguments. I followed this guide here, though it is outdated and some KEXTs have been merged with WhateverGreen. Sometimes instead of a full freeze / crash, the sample rate of audio will just drop significantly, causing a lot of aliasing. The system otherwise works as normal, with only audio related functions breaking. It feels random but seems to correlate with playing youtube videos, streaming audio in Finder, playing sound files from chat clients like Telegram/Discord and such. Ever since installing my new Sapphire Radeon Pulse RX580, I've been having issues with audio freezing up for the whole system- seemingly the coreaudiod process crashing / my USB audio interface not working.
