I used several Coreelec boxes before and all with the same TV, AVR, all of them S905X3 and one Vontar S905X4.
All of them worked fine, shut down when the TV was shut down, and started right up, when the TV and AVR where turned on.
This does NOT work with the Tanix TX4. No matter what I change in CEC settings of the box it just shutsdown and won’t get woken up.
And idea what I can do? Any logs to share so you can check them?
Thanks in advance!
