What is the easiest way to accomplish this? Have a friend asking for help and here is his setup... Large outdoor pool house area has TV and four ceiling speakers. He doesn't want to have them as a surround format, but rather playing the same 2-channel audio from the receiver whether it be TV or music. Is there a setting on the Yamaha receiver to accomplish this or does he need to run something like a separate amp or impedance-matching switch? He'd rather use the receiver since he has it and it will handle the HDMI inputs to the TV.
