Hdmi cec no fixed since launch xbox series!!

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.

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?

Xbox One supports HDMI-CEC.

I don't know what anynet is, nor do I know if "HDMI control" and HDMI-CEC are the same thing, but HDMI-CEC is supported according to MS.
