soundbar no sound

Solution
First, is the HDMI jack it is plugged into an HDMI (ARC) jack? It needs to be the one that is ARC. If it does not have one that is ARC, I think you will need to use a connection other than ARC. And from what I have read on some tv's you have to go into the tv menu and activate ARC.
