Those home theater in a box are not very good and are not flexible for adding anything to them or for up grading. This is a common issue with consumers that buy one, then find out they can not connect the tv to it to hear the sound from the tv. They are mainly designed for you to watch a movie with surround sound on the built in player. Your tv only provides you with an optical audio output, this is a digital signal that has multi channel information and has to be decoded by a multi channel receiver, home theater in a box with an optical audio input or a sound bar. If you system does not have an optical audio input then you are not going to be able to hear the sound coming from the tv. Hope this will help you out.
