Currently I have 4 rock speakers around the pool and 2 Bose 151s under the soffits at the house. I am running an old bookshelf system and a 4 zone switch. I have a RCA cable from the video input to the headphone jack on an old windows xp machine. I am able to play radio from the bookshelf system and pandora or iTunes from the computer. I would like to be able to AirPlay somehow. I have searched for a 2 channel receiver with networking and AirPlay but I can't find anything. Any ideas how to do this?
