My Samsung smart tv seems to have 2-3 hdmi ports, but no arc like people have talked about. So my Samsung sound bar has to be connected with the optical cable. The annoying problem is, I have to use use 2 remotes to watch tv?
And if any of that doesn't work, just go pick up a Logitech Harmony remote. Its what I did to get my Panny Plasma to work with my Samsung sound bad. You can bundle it all nice and simple. http/www.logitech.com/en-us/harmony-remotes
