I don't understand what you are saying. I run Optical / Digital with the TV speakers turned down so low you can not hear them, they are basically turned off without having to actualy turn them off. All sounds come thru my Yamaha and the the surround sound speakers and sub woofers. When I run the TV speakers, the Yamaha is not even turned on. The red and white cables are run directly to the TV from the DTV receiver and do not go to the Yamaha. To me, I run either or and not mixed.
