I had a strange issue a few days ago but I don't know if it is related to headphoned: I unplugged my headset while playing music, the music stopped as expected. After a few days and a few restarts I plugged in my headset again and it began to play from the last active source in the default media player which was not what I wanted (maybe this behaviour could be useful for a short time after unplugging but not after a few days + restarts).
Can it be related to headphoned?
