So I have my Tivo and Receiver hooked to my TV with a HDMI cable. Everything works great. However, when I try to listen to Pandora through my TV, the television program continues to be the only audio I hear. If I switch my receiver to Aux from HDMI, then the TV will play the Pandora music through the TV speakers, but I want the Pandora music to come through my home theatre system. Any ideas??
