Just switched my Raspbery Pi 3 from LibreELEC last release to OSMC.
I’m struggling to get my TV remote to work via CEC as it did with LibreELEC. With OSMC, buttons like stop, pause… aren’t working in Live TV. They all were working with LibreELEC.
I tried Keymap editor, but OSMC doesn’t register when I press some of these keys on my remote.
Thanks, as fzinken said, was only a problem of “sync” between the TV and the Raspberry. Just a matter of powering off both devices for some minutes, now it’s working flawlessly.
