Apple TV stuck playing music

Hi,

I had a problem with my AppleTV 3rd gen stuck in music playback mode which would not accept any new Airplay/Mirroring sessions from iOS 7.1 iPhone4 and iPad Air after that. Flicking through menus worked fine.

Once I pulled the power, waited a few seconds, powered back on and only then could I get Airplay/Mirroring working agan.

Has anyone else seen this issue?

Cheers.
