I have a Samsung HD TV, a blue ray dvd player, and a surround sound where the speakers plug into a regular DVD player. How can I get the surround sound to work with the blue ray player? Right now I can't do both. I can only use the blue ray with TV sound, or the regular dvd with the surround sound. I was able to get surround sound with blu-ray but the sound is extremely low and has static. The volume controls do not work to control the sound. The blu-ray only has coaxial port. Looking for any suggestions please.
