I do not have the Pi2Design 502DAC Pro so can't test directly. I do have a HiFiBerry DAC+ Pro which uses the same driver (after all, it was written for it!).
Just now dug the DAC out of the drawer and plugged it into an RPi4B/4GB, installed moOde6.0rev2, and powered up. I'm listening to the Jazz Groove on my audio system plugged into the RCA jacks on the DAC. Sounds fine.
Don't worry about that stream of "not registered" messages during the boot sequence. I think I started seeing them with these drivers when Raspbian Stretch was introduced or maybe even before. The one which matters is the final message saying the mapping is ok. Here's what I'm seeing on my system:
If there is an issue with RPi4B GPIO pins and the Pi2Design 502DAC Pro then I think it's up to Pi2Design folks to explain it. Only they know what their board is doing at the interface.
