It started several days ago after USB speakers were connected and disconnected, A restart would fix the problem...but not anymore .
Update..... Pulled the batterypack out, and the plug , held the start button for 30 seconds and restarted without the battery ..It worked. (But I still need to know what causes this glithch?)
