I have an Ipad 2 with a Denon 3312-CI receiver. I synched the ipad to my PC and the music loaded under the music icon on the ipad. I have also downloaded the denon app on the ipad. I cannot find the airplay button on the ipad? My ipad came loaded with the i tunes app but it has the store only whereas my pc has itunes with a toolbar on top and the library, store,shared, geniues, etc on the left side. I would appreciate any help so I can stream music through my home theater system using air play.
