HDMI CEC Control

[PeteRyde]

Does CEC control work from the IceBox to TV via HDMI-CEC? I dont think so based on the guide suggesting I need dongles but thought I would ask.
The Kodi Wiki suggests that CEC control is built into Kodi but that the hardware and OS would need to support it.
All I would like is the IceBox remote to turn up/down the volume on the TV rather than the volume level of the IceBox output.
