[SOLVED] Disable HDMI-CEC or whatever causing receiver input switch

[YujiTFD]

Hello.

UPDATE: solution found, see #5.

I wasn't able to find a HDMI-CEC support mention in moOde, so I'm flying blind here, but whatever it is, here is my story :)

I have an AV-setup with several sources connected to the receiver, which is being controlled via Logitech Harmony Elite remote, but still have to have HDMI-CEC since it's the only plausible way to operate Apple TV with. So moOde always, and I mean always trying to switch receiver input for itself: moOde input is active every time I switch receiver on regardless of previous activity, and should I launch "Watch TV" or "Playstation" scenario, I see receiver select corresponding HDMI-input and rolling back to "mOode" having me to choose needed input again to make it work; it's really inconvinient and annoying.
In the worst case I can use USB DAC for output, making HDMI-CEC irrelevant, but I really don't like the idea of audio double conversion (USB DAC -> receiver).
What's causing such behaviour and how can I switch it off?

Thank you.

and you have supplied some detail..?  Moode version, Pi ? , Network ? Peripherals ?, power supply ?, output from the Moode menu "System Info" ?  and 'Audio Info"    and Your 'Whatever' ? lol
 
If we were mind-readers we would have fixed it before you reported it

What's causing such behaviour and how can I switch it off?

Your receiver ?

Without any detail the community is "flying blind " here too..

DRONE7, moOde is 6.7.1 fresh install (why would I ask before trying update?), Pi4. Can't see how network and power supply are relevant, but they're ina block below, direct HDMI connection to receiver, otherwise CEC wouldn't work, no peripherials. Since I said I need HDMI-CEC for Apple TV, I do not need to disable it on receiver, but it's Marantz SR6012 - was it useful?
I don't mean to sound condescending, but I did ask about a setting regarding HDMI-CEC in moOde in case I overlooked it - and you bathed me in sarcasm. 'Twas nice.

@YujiTFD

No, there're aren't any moOde-specific settings pertaining to HDMI-CEC. However, moOde lives in the RPi hardware/firmware/software ecosystem and if you read the RPI documentation you can find useful information about disabling HDMI-CEC in the booting process.

Video options in config.txt

Have a look at, for example, hdmi_ignore_cec

If playing with these configuration settings isn't helpful, then I suggest you follow up with posts to the Raspberry Pi forum.

@TheOldPresbyope, that's what I wanted to know, thank you. Still learning Pi =/

UPDATE.
When I realised where to look, issue has been solved it very quickly:

Code:

sudo nano /boot/config.txt

add two lines:

Code:

hdmi_ignore_cec_init=1
hdmi_ignore_cec=1

Reboot. Done, you're amazing!

Without "hdmi_ignore_cec_init=1" Pi still waking up CEC-enabled devices, so I had to prevent initial handshake too.

Thanks again!

P.S. It seems to be a very old issue with Pi.
