on the back of my Emerson hd tv it says LC220ML i THINK IT IS A 22INCH HDTV HAS HDMI 1 AND TWO. TRYING TO HOOKIT UP TO A NEWER ZVOX HOME SPEAKER UNIT IT IS THE NEXT TWO THE HIGHEST PRICED MODEL. CAN NOT GET A GOOD SOUND OUT OF IT. iT WAS WORKING FINE WITH A EARLY MODEL ZVOX WITH HDMI 2 AND USING THE EARPHONE JACK. DOES IT HAVE ANOTHER AUDIO OUT PORT OTHER THAN THE EARPHONE JACK THAT WOULD WORK WITH A ROKU PLAYER USING HDMI 2. IS THERE A AUDIO OUT ON THE BACK? IT'S PROBABLY ONE OF THE FIRST HDTV'S
