Okay, so I'm running Spotify Premium on the iPad wirelessly through my stereo using Airplay. Sounds great, loads of music. But if someone plays a game or does anything else with sound effects on the iPad at the same time, those sounds are coming through the stereo, too, which slightly lowers its value as a way of playing music! This never happens using Airply (or Airfoil for that matter) on my Mac laptop. Is there something I can change in the settings to stop this happening?
