Based on this thread I decided to test a Sonos Connect with a the ZA3000ES but I'm not seeing the solid integration reported here. Once the Connect starts playing it can take several minutes for the AVR to notice and turn itself on. Going in the other direction, changing the input or turning off the receiver causes Sonos to pause almost instantaneously so there isn't a network connectivity issue. Is there some setting I'm overlooking to get this working right?
