I have 4 speakers inside and 2 speakers outside. I am trying to set up so I can have each zone show separately via airplay. I set up 2 zones via the MusicCast app, but only the main zone shows on airplay. Any suggestions on how to get both zones to show via airplay? Thanks!
Airplay only sees the device and in this case that device would be the AV receiver. It is the AV receiver that is facilitating the two zones and Airplay only sees the device and not those 2 zones independently. You'd need to send the Airplay audio to the AV recever and then set the main room and the second zone to the Airplay source. The 2 zones will not be independently selectable via Airplay because they are the same device.
Note that:AirPlay is only available in Zone2 when AirPlay playback is ongoing in the main zone.
