i’m newbie of mopidy. sorry for mostly(maybe) fixed problems. i install to debian virtual server. But show this errors via mopidy.log file.
[24110:MainThread] mopidy.audio.gst: GStreamer error: state change failed and some element failed to post a proper error message with the reason for the failure.
trick: i use the virtual server via KVM and debian 7.x server(not gui or X11)
