Equipment involved: New ATV, Sony LCD TV with 2 HDMI inputs, DishTV sat box, Sony home theater and HDMI splitter with 3 inputs and 1 output. Problem/Situation: I can't currently use my ATV audio through my home theater. I am running the Dish and ATV into the HDMI splitter then into TV. The home theater (dvd) has it's own HDMI wiring into the TV. I need a block diagram and/or instructions on how to set up the equipment so I can see/listen to ATV, dvds and Dish through speakers of home theater. Currently the only thing playing through home theater are dvds. Thanks for any help you can give me.
