IIRC the Pi-4B changed how some of the GPIO pins operate. Maybe this is affecting the 502 board?
Yes, before I started using Moode I had to tell Volumio the device was a hifiberry digi+ pro. I had read that the Pi 4 40 pin header retained backward compatibility with previous HATs - is this something that can potentially be fixed by an update to the overlay, or would I need to look at replacing the HAT with one known to work with the Pi 4? (If so, is there a list of "known good" HATs anywhere?
I grepped dmesg for sound related output and got this:
