After experimenting a little with airplay (with mixed results, at times it works great and at times it locks) my system ended in a weird state in which I am not able to play regular music (from MPD database) anymore.
If I go to Library I get the usual "Browse your library" screen, but when I click on the USB storage icon (or any other for that matter) I get the "Playback source" menu with the options "MPD, Spotify, Airplay, DLNA". After clicking "MPD" the previous screen comes back but the only thing I can have is the same menu, over and over.
Here is the debug info (if relevant)
Is there a way to have music playing again without having to reset the whole system by installing everything from scratch?
