Um?// OK..the sound bar came with a red and white plug..nothing more in back except the power jack and antenna jack..the red and white on back of my Westinghouse TV , says av-input..for the red and white plug.i know I need a adapter, but what sort..the DAC in photo looks good..I'm no computer wizard and a disabled Veteran..I just like to know , when I head out to the tore I know exactly what I need, so I'm not sold then wrong thing.I take a cab everywhere I go..so a positve answer is appreciated. I seen a video where the extension had a head phone jack with the red and white plug...and that u plug the jack in because the head phone jack would release the sound to the soundbar..is this right..I'm lost..lol
