We figured out how to connect the computer to the HDTV to display, only thing is the sound comes from the stereo speakers hooked up to the computer. How do we connect sound from the TV instead of the computer speakers (external speaker system?) We have outlets for every kind of cord but not sure exactly whast to use and where.
