Just set up Airplay a couple weeks ago, everything seemed to work fine streaming music from iPhone 4s and iPad (3rd of 4th gen, can't remember, its the retina one)...
I think I remember it automatically detecting my command from the phone or iPad. Now I get nothing from either. When I chose the airplay source it illuminates in orange, whereas I think it used to be blue when it was working.
May or may not be a coincidence, but I updated firmware recently, and iOS, but I'm pretty sure everything was working since then. but not for very long.
sound familiar to anyone??
