So I swapped a Denon AVR-2312Ci from one system to a different one. I want to run AirPlay but can't quite figure it out. - I plugged it in via Ethernet and I *guess* it is connected to the network: "Network Connecting": DHCP ON Obtain IP address automatically, there is a MAC address shown. - Page 73 of the manual says "Launch iTunes and click the AirPlay icon" but I don't see that. Basically I think all these instructions are out of date. - On my iPhone I don't see where to connect AirPlay-I thought it was the menu that swipes up from the home screen but I don't see anything. On my MacBook Air, I don't see an icon on the top menu to select where the audio output goes-just the volume slider, with no choices. Nor any AirPlay icon - AirPort utility says no other WiFi devices discovered, for what that's worth. ???
