Ok I bought TNP Digital to Analog Audio Converter Box Adapter and a digital coaxial cable. It's a very straight forward hook up. I ran the coaxial cable from the TV to the converter box coaxial input. The box has a red and white RCA output and a head phone jack. I am trying to get my TV to play through a set of self powered speakers. I plug the speakers in the headphone jack and all I get is a bunch of loud chatter. I do not know if my brand new TNP Digital to Analog Audio Converter Box Adapter is just bad or if something else is wrong. Any Ideas? This is the one I purchased.
