I confirm that it works great on RPI 5, thank you very much, the problem is solvedI spoke too soon - the penny has dropped. Fixing the obvious Pi4 -> Pi 5 difference does make runtime soundcard overlays work if the modules on your Pi 5 match the kernel.
There's a Pull Request in our kernel repo (https://github.com/raspberrypi/linux/pull/6051) that removes the difference. Installing a trial build ("sudo rpi-update pulls/6051" in about 40 minutes, after the auto-builds have completed) should allow your original overlay to work.
