I'm puzzled with my new Raspi4. I installed libreelec on it and restored the backup from my Raspi3 (same, latest LE version).
Everything is there and works as expected - except my IR remote. (logitech harmony)
I've connected the same IR receiver to the GPIO pins and set "dtoverlay=gpio-ir" in the config.txt
What could be wrong?
I even tried a clean reinstall because I read that the MCE IR should work out of the box - but no luck.
Interestingly: reinstalling the RPi3 with latest libreelec version, restoring the backup and setting "dtoverlay=gpio-ir" leads to a working IR remote on the old RP3. Why not on the RPi4?
Thanks for ANY hints!
PS: I followed Infrared Remotes [LibreELEC.wiki] but the debugging doesn't work like described. E.g. "ir-keytable -t" doesn't show any of my IR keys. It's very strange however that it shows scancodes from a third party remote: Why not from the Harmony? (BTW the exact same happens on the RPi3 where the IR remote is working - I'm confused)
