If you've got your system running near to perfect then you can share your success story here.
After banging my head against the wall on a few steps, my RyzenTosh build is mostly functional.
Followed xJetSetLifex's guide based on common hardware.

OpenCore 0.5.3/0.5.4 0.5.5/Catalina 10.15.2 10.15.3
rEFInd graphical boot menu

Key Hardware Components:
  • Asus X570 TUF Gaming Wi-Fi
  • AMD Ryzen 5 3600
  • Crucial Ballistix Sport LT 32 GB (2 x 16 GB) DDR4-3200 @ 3533
  • Sapphire Pulse Radeon RX 5000XT Nitro+ RX 580
  • DisplayPort & HDMI outputs working
  • CPU core count reported correctly - 12 cores shown in Activity Monitor
  • Video card/GPU being properly detected
  • Realtek S1200A Audio Codec (Tracked down device path using gfxutil and troubleshooting page from the OC Vanilla Desktop Guide)
  • Memory type/speed/amount properly detected
  • NVMe & SATA storage devices
  • Realtek Gigabit network adaptor
  • Apple account related functionality (Messaging, App store, etc)
Open Issues:
  • No audio device found by MacOS
  • Sleep Panic
  • Odd behavior with VLC (Locks after scrubbing timeline: Was OK once audio device was fixed/available)
  • Screen completely scrambled when attempting to use Kodi with RX 5500XT, so I reverted back to RX 580
Any advice on fixing the above would be appreciated, and will update post with Kext & .plist details.

After additional testing, I'm only getting stereo audio out, so I probably have to try a different layout.

success for me. thanks for the info and guide. used your Efi and plist without any changes whatsoever. did not install clover via GitHub but layed OC over the usb for boot and dropped Efi directly down onto that. Although I don't have bluetooth or wifi. I have not had any issues whatsoever so far. thanks again.
