Yes， it is supported, but need to confirm your TV has the CEC function first
Please connect the Soundbar and TV with an HDMI cable and force to open the (ARC)PCM &TV CEC function.
Users are able to control multiple smart devices using a single remote control via CEC enabled, thus eliminating the need to use multiple remotes to control devices
1. Volume control: Through the TV remote control, you can simply control the Soundbar, such as adjusting the volume of the Soundbar, mute, and other functions (can be separated from the Soundbar remote control to control the soundbar volume, mute, etc.)
2. Power on/standby control: When using the TV remote control to control the TV on/off, you can simultaneously control the TV and Soundbar to switch on/off simultaneously, eliminating complicated operations
Note: The CEC function is not supported on the TV Stick
Please check the attached document for the setup method for different TVs
