I have read several threads here but none to help me with my issue. My box is connected to my Panasonic Surround sound system. It plays through my surround sound system fine. It will not how ever have sound to a pair of wireless head phone I have connected through the optical out of my surround sound system nor send sound to my TV. How ever my cable box that goes through my Panasonic will give sound on the TV and wireless head phones. So will anything else connected. I have tried several configurations on both the Panasonic and my box. I believe that it has something to do with the audio format that the box transmits in, but not that up on it. Please any advise would be helpful. Thank you.
