Has anyone had any trouble getting Airplay Audio working? It seems fine through iTunes, but when changing the whole system audio to Airplay, rather than internal, nothing happens.
Yes, same problem here. I normally play videos from my MBA through a projector connected to Apple TV and airplay audio through speakers connected to Airport express. Now, the videos won't play...they freeze when I change the system audio to airplay. When i change it to 'internal speakers', the videos play fine. So, my entire home-theatre experience has come to a standstill for the time being
