I'm having the same issue on WEtek Play, is there a fix for wetek play?
For details see: thread-4845.html
Same here with Wetek Core. I have been using Android so far, but since the PlayStore KODI Krypton update screwed up the hw acceleration, I switched to Libreelec on SD. Now CEC is not working properly. It sort-of starts and works for a few seconds, but then it stops working. Yesterday it worked for a few hours before stopping. Sometimes it starts when I reboot Libreelec, sometimes not. Both TV (Philips Easylink) and KODI (settings-peripherals) options are turned on.
Is there anythong that can be done? I hate juggling more remotes than necessary.
