Please provide the model number of the Sony product(s) that you are using so that we can assist you better. If the Blu-ray Disc player or the Receiver that you are using is not a Sony product, then provide the jacks available in the unit for audio connection.
Sony (& other makers of blu-ray players) has eliminated many connection options in their newer players. Unless your receiver has a digital coax audio input jack, or can handle audio off hdmi, you are out of luck with this model player. You were better off with your S580 (imho).
