Cannot AirPlay audio to ATV 3rd Gen
In addition to an ATV connected to my TV, I have three Airport Expresses in other rooms. From my iPad, if I want to AirPlay audio, for example music or content from the BBC Radio app, when I "flick up" from the bottom of the screen and select AirPlay I can see my iPad, my ATV and all Airport Expresses. Although the audio will play to all the AEs if I select ATV, a tick appears but the sound immediately jumps back to the iPad. There is no way I can get the sound through the ATV. Mirroring makes no difference either.
Amy ideas please? Thanks.
