Play oldest recorded noise first when playing all

Given the expiration time of the recorded sounds and me not re-playing them every morning, I sometimes get to the situation when they get auto-deleted before I manage to play them. And every day there are new ones.
I would greet the opportunity to play the oldest ones first.
