I really like to listen to some music with my earphones, but I often fall asleep so that the earphones are still plugged in, but not anymore in my ears. In the morning the alarm goes off, but I don't wake up, because I cannot hear the alarm with the earphones since they are not anymore in my ears. I suggest to create a way or an alarm-app to override the earphone with the alarmclock.
Maybe there is a way to do it, but I think it is an hardware thing.
