Hello. I am curious if I can use an Airport Express as an Airplay only device?? I want to stream music to my AVR from my Mac all within the same room. Currently the Airplay signal has to go from nearly one end of my apartment (bedroom) to the other end (living room) and back again to go from my Mac to my Apple TV. Both of which are in the same room. It's my Airport Extreme (and Rogers modem) which are in the living room. Is this a possible option?
