XBOX Series X CEC Partially not working

Hello 打つ,

I will keep looking for a possible fix and will update the post if I find something new.

I tested the steps you mentioned in this last message with my TV.

I have an LG C3 OLED, it does the same thing.

Hello Rodrigo, I have tried both energy saving and the suspend options.

Apparently this happens when you turn the system remotely by pressing the Guide button on the controller. Sometimes (not all) when you turn the system by pressing the power button on the console itself, CEC kicks in and the TV turns on. Also, resetting CEC in the settings (disabling, restarting, enabling cec and restarting) makes the Series X turn the TV, which makes me think it's not related to the TV CEC configuration, or a hardware or cable failure, since it only fails when turning the system from the controller I think it can be assumed that the problem is on the software side.

I will check the reddit, though I don't use reddit myself, for more help, thanks for the resource. I will be waiting for more responses and hopefully by me making noise here someone at microsoft notices there's a bug with CEC in their high end videogame console.

Cheers

I am sorry to hear that.

Which Power mode are you using the console?

Have you tried to switch the Energy mode to Shut Down (Power Saving)?

Please, follow these steps:

Press the Xbox button to open the guide.

Select Profile & system > Settings > General > Power options.

Select the Shutdown (energy saving) option.

Another thing you can do is report this issue on the Xbox Insiders Reddit Forums*.

It's the fastest way to have your request heard.

I hope this helps.

Hi TexasMaster9351! My name is Ricardo an independent advisor ready to help you with this situation!

HDMI-CEC is supported only on Xbox One X, Xbox Series S, and Xbox Series X. You must also enable HDMI-CEC on your TV.

Xbox Series X|S consoles can use an HDMI feature called Consumer Electronics Control (CEC) to send commands to and from CEC-enabled devices (such as TVs and AVRs) that are connected to the console.

This feature can be turned on and off via the TV & A/V power options settings screen. Press the Xbox button  to open the guide, then go to Profile & system > Settings > General > Sleep mode & startup > TV & A/V power options.

Update, I disabled eARC and HDMI ON to OFF on the Denon receiver. And on the TV, I also disabled eARC. On the Xbox series X I disabled CEC and ever since then I haven't had an issue with the audio. I did notice when I enabled CEC on the Xbox, and choosing Dolby Atmos I lost audio intermittently, so I just left CEC off. Unfortunately I have to use 3 controllers to turn everything on now. Now I can choose different audio formats with no audio loss.
