I have a Retina MacBook Pro 15" and a Mac Mini Server. I'm using the Server mainly as a media server. I bought a few Bowers and Wilkins AirPlay speakers, they sound amazing. What I want to do is Airplay my movie to AppleTV and my audio to my B&W AirPlay speakers. I have gotten this to work but the audio doesn't play to multiple. Is there a way to do this? What am I missing? AirPlay to multiple works great on music but seems to limit you to only one speaker form movies.
