My Kodi is always powered on and I do not use HDMI-CEC. I even had it switched off for a long time but that makes no different. I have it on now with no shut-downs in there on activity on my TV.
I have a Raspi running Kodi 17.3. But when I switch my TV from my regular TV decoder to the HDMI port of the Raspi it seems to shutdown most of the times. It this something known? Does anyone have tips?
