[PROBLEM] Can not control XMBC through CEC HDMI Onkyo AVR with it's remote control

[jakenl]

With the cec-client command I see no response with the physical remote of the receiver, but with the Onkyo app on my phone, cec-client detects all buttons with the right text (like stop/play/pause/top/left/right/down/green/yellow/red/blue) etc. Unfortunately neither the physical nor the 'virtual' remote (the app) does a thing in Kodi. I tried to change the paramater 'Physical address'(overwrite HDMI Port' from the default 0 to 1 (the port on the AVR where the RPI is connected to). This value doesn't 'stick' but is lost during reboot.
On the Pulse CEC-adapter Wiki I see that there is an option to change to what HDMI device the adapter is connected to (0=TV and 5=AVR)., where 0 is default. I don't see that option within XBMC

Edit: I ran cec-client -m for a while and tried other things, like physical port 1000 (more for non-CEC capable amplifiers). When I entered the XBMC CECadapter setup once again, I all of a sudden could select the HDMI port (which is 1 in my case) + the option to select to what source it is connected (TV or Amplifier). I set that all correct and hurray, via the Onkyo app I now can control the Kodi/XBMC. The physical Onkyo remote doesn't do anything still, I see no response during the cec-client -m monitoring either. The commands from the Onkyo app do come through 100%

After a reboot of Xbian, I don't see the HDMI port and connected device option anymore and I have no control through either the Onkyo app or remote itself. Now I don't even get it back.

Playing with the cec-client with a command like:
% echo "on 5" | cec-client -s
% echo "standby 5" | cec-client -s

works well. It turns off and on the Onkyo receiver without a problem.

I have no clue where the conflict Kodi < > Onkyo is in, definitely RPI and Onkyo are good friend on the command line
