I have installed Beatbox
but I can't set it as default music player in System Configuration
of Gnome-shell. How can I set it manually?
I add information:
BeatBox can't be actually define like default audio player in Gnome: https://bugs.launchpad.net/beat-box/+bug/972956
I want to know how can I define manually the default audio player in the same manner that I can define the default calendar app: How to change Gnome Shell calendar default application?
