Selecting other AirPlay speakers on AppleTV doesn't work
My AppleTV (ios 5.1.1) gets its AirPlay from the Airport Express (latest white puck running 7.6.2). I have a second Airport Express (7.6.1) in the office. Using iTunes, I can select multiple speakers and hear music from the Apple TV speakers + office speakers. Yay.
The problem comes when I use the AppleTV menu to select the office speakers. Nada. I thought the 5.1 release was supposed to enable what iTunes does using the AppleTV instead. But at the moment, I can't even get music to play just on the Airport Express-connected speakers.
