LG soundbar / LG tv issue. Any help appreciated thanks

[CC1977]

Hi. I have a 55UP75006LF tv and a NB3630A soundbar. Both are LG.

I can't seem to get the tv to link to the soundbar despite my best efforts.

I wonder whether anyone might be able to help please?

much appreciated.

If you're connecting by HDMI Arc check you’re using the correct HDMI Arc port on the TV (ARC is usually printed next to the socket) and select HDMI audio out in the TV's Sound output settings.
If these are already set unplug/switch off the TV and Soundbar at the power socket for 10 mins then power on again and try it.
