I am looking at getting a blue ray player very soon. My question is about how to hook up the audio with what I currently have. I already have a surround sound system and wanted to know if I should use optical cable directly to the sound system input or hook hdmi into the tv and run the digital audio into sound system from the tv? Oh, by the way, the only digital audio out from my tv will not fit into the digital optical input in the sound system. Do they make an adapter?
