Problem description:
Hello,
When I turn on amplifier, Xbian is switching input on amplifier to input where xbian is connected.
How can I disable this?

In /boot/config.txt I have hdmi_ignore_cec_init=1 but this as I understand concern turning on Xbian, not amplifier itself.
In /etc/default/xbmc I have all disabled/no.

I had OSMC before and then this problem didn't occur.
I don't want to disable CEC capability, because in Xbian it is working great! I can manage Xbian by projector remote.

Check Settings -> System -> Input Devices -> Peripherals -> CEC Adapter There maybe something in there.

Also you could try hdmi_ignore_cec=1

Thanks, I found this earlier and disabled both options which look like the ones I'm looking for, unfortunately nothing changed in Xbian behaviour.

Does hdmi_ignore_cec disable my projector remote?

Not too sure. I'm only guessing here. hdmi_ignore_cec will probably ignore CEC but might be worth a try.

Otherwise all out of ideas.
