Hi there, I am trying to connect my Sony PS2 to my Sony DAV-S500 home theatre using digital optical cable to get surround sound effects for discs played on my PS2; but I am not getting audio from my home theatre speakers. I've connected PS2 digital optical out to Video 2 in DAV-S500 (digital optical port is available only in video 2). I did not find any fault in the cable because I tested with a cable TV receiver connected to a dolby audio received (It was Sony, but I do not remember the model). Can someone help me out
