I can’t help but I get the same error message sometimes. I haven’t counted the exact number of times but it appears to happen about 1 in 3 reboots/power on. I can’t find a pattern as to what is causing it.
I did post a debug log in a previous thread a few days ago when it happened.
I’ll point out that I’m using a custom Amlogic-ng build which is the same as “coreelec-9.2” branch but with one kodi patch inserted into the build - that patch is mentioned here in a PR I submitted to Kodi a few weeks back. This patch removes one line of code from VideoPlayer.cpp. Link here:- https://github.com/xbmc/xbmc/issues/16390
This patch should have no impact on the CEC initialization error.
I tried 9.0.3 on my U9-H and I could not re-produce the issue on 2 TV’s I tested.
I think your issue may differ to the people with the N2.
I don’t know how this issue can be related to us as you say nothing changed in your setup and it just stopped working one day so I think maybe your U9-H has gone faulty.
Seems to be fixed now. I rebooted to the android tv rom i have on it to see if it worked there and it did then when i booted back to coreelec it worked. Don’t know why i didnt try this earlier >.<
