Downloaded a few albums using the iOS app last night. All the songs and tracklistings made it in like they should, but whenever I select a track it just counts down without playing any audio. I've tried using several different audio cords through my car, computer, and an external speaker, and of course tested my phone's speakers (yet it plays everything else normally). I transferred the albums (one artist at a time) using the foo_upnp component, but am not sure if that has anything to do with it. Any help would be appreciated.
