I have been using Kodi for a few months now on a RPi2 with Rasbian. 2 days ago, with no changes on my part, CEC control stopped working.
I have been trying to troubleshoot this myself, but everything seems to be working, only that it isn't responding to inputs.

If I use cec-client to monitor the connection, I can see Kodi and the TV talking during startup, after which point the TV starts sending button presses as they occur and Kodi specific things such as the name show correctly in the menus on the TV, except the controls, such as the arrows don't work.

I have tried most common debugging steps like restarting, using a different HDMI port, only plugging in the RPi, resetting settings, ... I have not tried wiping and reinstalling Kodi, which I suspect will fix it, but I only want to use as a last resort.

I enabled debug logging of CEC and can see kodi receiving the commands just fine.

Code:

I used the instructions from http://drcobra.co.uk/?p=25 to install Kodi

This seems to have fixed itself.
I didn't really change anything except to leave it alone for a while, disable the debug logging (which was only on to troubleshoot this), restart Kodi and turn the TV off and on (which I had done several times before).

1 thing I will note is that the Pulse8-CEC popup on boot showed for considerably longer since working. (was just a flash up then away, now a few seconds).

I can't see anything different in the logs that could explain this.
