: Hdmi cec problems since last update Xbox Series X LG TV and sound bar
I have problems with hdmi cec in xbox series x since last update. Before it worked perfectly, now with last update, now when i’m playing with my tv speakers suddenly the xbox turns on my sound bar randomly. And when i power off my xbox series x always turns on my sound bar itself! Please fix it as it was before. I have LG tv and LG sound bar.

I'm going off that the OP was going to connect the Xbox to the sound bar then the sound bar to the TV, this route would require the sound bar to have HDMI 2.1 to retain 4K at 120hz for the TV

"If I hook up my series x to sounder and sounder to my LG CX"

"So if I pass the xbox through soundbar to tv, not sure if I will lose some of the features (VRR, 4k 120FPs, etc)?"

If they can connect the Xbox straight to the TV then the TV connects to the sound bar, they should be fine and everything works.

Just had to say.... I've had to disconnect the hdmi from the xbox as the sound was just too much. Plug the sky box into the TV and problems sorted. My setup is sky hd box --- hdmi to xbox ----hdmi to tv. Sound is an lg sound bar on an optical cable direct
from the tv.

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.
