my airplay mirrors video but not audio
I recently purchased an AppleTV and it has worked just fine and mirrored tv content from my MacBook Pro. Tonight for some reason it will not mirror the audio and I haven't changed any settings. I tried all the suggestions on the AppleTV support website--changing the audio to 16bit, turning the dolby off, resetting the Appletv etc and so far nothing has worked ... ??
