hi i have Sony blue ray bdps3500 and Samsung LCD ln-t-4053h. blue ray has orange plug for coaxial digital audio-the TV has a digital audio out optical plug looks like a house.what wire can be used to connect these too for audio sound.Sony drops audio sound and is hooked up by HDMI right now-but have had problems before and replace that numerous times-have to have TV hooked up with red and white.and the sound works great now.the sound on the blue ray will also drop when watch a disc.i do not have anything else hookup to the TV-no soundbar or extra speakers.
