I have a 65" TCL UHD 4K tv and have just bought a Sony HT-CT790 Soundbar. I am unable to get the sound to work via ARC. Will only work when I connect an optical cable between the soundbar and TV. I have installed the soundbar as per the instruction manual and my TV does have ARC
 
If both pieces are ARC capable it should work. Notice only one of the port on the TV is ARC, not all. And don't think for a moment all plug&play, you may have to get into the menus and explicitly enable ARC..... they make things complicated to keep us geeks employed! :D

I have 4 HDMI ports on the TV and only HDMI 4 is marked with ARC. This is where the soundbar HDMI cable is plugged into.

There is no option in settings to turn this on unless it is called something else in settings
