Hello! I have been trying to solve this puzzle for some time and am hoping someone here can help. I want my Apple TV allow me to use AirPlay to stream music to it WITHOUT having to turn on my Plasma TV. I have HDMI going to the TV. I have Optical (Toselink SP?) going to my Yamaha receiver (No HDMI ins). When I set the receiver to the input I connected the optical nothing... As a note I am also running optical out of the TV to a different input for viewing TV and listening with the receiver. Anyone have any suggestions for me? Much appreciated!
