I've literally been through every way to make the audio work and its not working. My Tv is a samsung LCD Tv. Its model number is ln40c500f3fxza. And it is hdmi/dvi .
I have both the Hdmi cable and the Optical cable and still no noise besides the high pitch one its making. I even bought a new hdmi cable to see if that was the problem
and it wasn't. Can someone help me or tell me what may be wrong?
