We just bought a new emerson 55" tv, and I ordered a Panasonic home theatre soundbar model number - sc- htb170 , but in trying to install it to the tv , there's only one hdm1 plug , and that's where the cable goes in, and also there is no audio output on the tv......with the same kind of plug as the home theatre soundbar so we need to know our options ? I read about hdm1 switcher boxes ? Would that remedy the situation? Or what other options could you suggest ?
