Feedback: HDMI-CEC not working when turning the system on

Don't count on Microsoft adding HDMI-CEC. That would require you to turn on your cable box first and not the X1. And that assuming cable boxes have HDMI-CEC capabilities (I don't have cable so I don't know, but my HD antenna converter box does not support
CEC). Unless they somehow send a distinct IR signal to the cable box and use HDMI-CEC through the X1 to the TV/audio receiver. And isn't HDMI-CEC send the signal up to turn on and comes down to turn off. Wouldn't that mean you'd turn your X1 on to turn your
entertainment systems all on and have to turn your TV off to turn everything off?

Just any random device? How does this work extensively? Does this just enable CEC on the primary HDMI out or is there some weird trick to plugging in my receiver to the HDMI in on the xbox and the input turns into the output but with HDMI CEC?

Hi, Tim. My name is Ron, I'm an independent advisor. I will be more than happy to help you.

Make sure to check first if your TV support the HDMI-CEC feature which sends commands to and from CEC-enabled devices (such as TVs and AVRs) that are connected to the console.

To turn off the TV along with the console, please do the steps below using your console.

Press the Xbox button  to open the guide, then go to Profile & System> Settings > General > TV & display options > TV & A/V power options.

You will need to turn on the HDMI-CEC function there, please also make sure that HDMI-CEC is also enabled on your TV settings.

After setting all of that up, on the TV & AV power options screen check the HDMI-CEC box to activate CEC then turn on the following setting "Console Turns off other devices."
