I have a Denon AVR-X3300 that I control via IP using Simple Control. It all works great except for one thing. I cannot find a way to select Airplay as a source for zone 2. In fact, I cannot find a way to select Airplay for zone 2 even from the factory remote! The only way I can select Airplay for zone 2 is from the front panel by pushing the “Zone 2 Source” button repeatedly until it selects Airplay. Has anyone figured this out? There must be a way to do this.
