TB3 not working consistently on Catalina

[kentkercher]

Using same CPU, motherboard, BIOS settings, OC 0.6.0.

I don't even know about hot-plugging yet—I can't get already-attached devices to work!

Which devices are you having issues with?

[kentkercher]

RME UFX+ audio interface—it's a TB2 device (which shouldn't matter?) connected via an Apple TB2>TB3 adapter.

Also, now that I think about it, the BIOS isn't exactly the same. I'm using the latest, F5.

I have a LG 5K Ultrafine, connects to the motherboard TB3 port, but the monitor's camera/speaker/mic are suddenly stopped working. It worked when the system was first installed.

I have the LG 4K Ultrafine and everytime I restart my computer, it does not recognize it as an audio output even though the display is on. All I have to do is unplug and replug in the TB3 cable from the monitor and then it recognizes the output. Sometimes I have to toggle it to be the display in macOS. Maybe this could be the same issue? I've been just living with it because it's so small and easy to do, let alone I don't restart/shutdown my device often.

I have tried your method, but still no luck on fixing this :P

@pekflyer I have had a couple issues where it won't recognize, which is becoming quite annoying. I've tried a number of things, but loading optimized defaults in BIOS and then going back adjusting them to the Chris's suggested settings again (in the latest EFI) seems to do the trick. Not sure what's causing this issue...

LOL, guess what, I just did what you mentioned above, and my LG 5K works like a charm now!!! I am so thrilled.
