Have Apple TV, Macbook, iPad and iPhone 4. All updated to the latest OS versions. Movies (including youtube) streams fine from iPad or iPhone to Apple TV using Airplay. But music alone won't. So if I play a song on iPod/iPad or Pandora, I get the Airplay icon, I select Apple TV, but no audio comes out of the apple tv. It thinks it is streaming, but it isn't. But movies (with the corresponding audio) streams to Apple TV fine. On the other hand, music from my macbook goes to Apple TV fine. It is just streaming music from iPad and iPhone that doesn't work. Note, my problem is not that I don't get the Airplay icon-- I do. It just thinks that it is streaming and nothing is happening. I've rebooted Apple TV, iPhone and iPad. No success. Anyone else seeing this? Any thoughts?
