I have a Pioneer XW-SMA1 and a Sony xperia Z I can not connect the 2 for wireless playback through Spotify. I also have the same problem from Spotify and my Mac to the Pioneer. Help!
Spotify on android does not stream over airplay or DLNA but your Mac should. There have been a few reports recently of airplay not working on Mac. Maybe post in the relevant thread and keep an eye on it for updates.
