Ok i have HDMI from ps3 to tv, then i have optical from ps3 to reciever. Im not getting any sound to my surround sound, if i turn my reciever off and use tv only i get sound through the tv speakers. Never had problem before. Oh, also if i hook up my Xbox360 exactly as described above the sound works perfectly through receiver surround sound. Bad optical port on ps3 or incorrect audio settings on ps3? Any thoughts?
