Xbox Series X disables HDMI CEC / ARC connectivity from TV (LG) to Amplifier (Yamaha)

Have you checked the TV itself?

I have an LG TV (different model) and sometimes HDMI-CEC is disabled on my Xbox One X's HDMI input after I change audio output (if I want to use my headphones for a while, for example). Its weird, I've never been able to get to the bottom of why
it happens but, sure enough, go to my TV's general settings while on the HDMI input and SIMPLINK (LG's name for HDMI-CEC) is off. Turn it back on and I'm good to go.

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.

Can you explain this a bit more? I have a slightly different setup and trying to get it to work.

I have the following:

- Comcast Settop box

- Xbox one

- Yamaha receiver

- LG TV

I have connected:

Settop to Xbox, through HDMI

Xbox to Yamaha, through HDMI

LG TV was already connected to Yamaha, and I have been switching everything thorough Yamaha already.

Everything works fine except one thing - audio for Live TV. I have audio for games, video, etc, everything that comes from Xbox directly. Live TV video works, but no audio. I have gone through the Live TV setup and Xbox correctly controls the settop box
(channels up/down).

Previously the settop box was connected directly to Yamaha, through the same HDMI, and everything worked.

Any ideas?

Just wondering what's the best way to setup my xbox, TV & Soundbar.

At the minute my xbox one x is connected to LG TV via hdmi and the TV and Yamaha Soundbar via hdmi (arc). Just wondering if it'd be better to connect the xbox to the Soundbar instead of TV (and leave the TV Soundbar connection via Arc as is).

It doesn't do ATMOS but does do surround and DTS.

Many thanks

IMO this is already the best scenario possible.

The first thing you must know is that every device have an inevitable input lag, the game mode in modern TV help to reduce it by turning off some image enhancement.

If you connect the Xbox One to the Soundbar, you may risk to add input lag because you have another device that must elaborate and pass video to the tv that can elaborate the video too.

I'm using an Xbox One X directly connected to a Samsung Q9FN 55" and a 7.1 audio system connected to HDMI ARC, my audio/tv don't support Dolby Atmos, but all works fine.

Yes the controller + adapter is up to date. The problem seems to be connected to how the console handles the hdmi output. It seems when the connection is not present anymore the console disables the output.

If somebody could test this on their console it could be really helpful. Basically change the input on the TV or Receiver the xbox is connected to and check if the headset still plays the xbox audio.

Maybe the issue is connected to my HDMI receiver and how it handles hdmi-switching. I also tried to disable HDMI-CEC and ARC but the problem still exists.
