Default sound always points to bark.ogg

[Oleg Moiseichuk]

When I create a new alarm the sound file "bark.ogg" is selected by default. As it is the first file in /usr/share/sounds/gnome/default/alerts/ (alphabetically), this sounds logical.
I would like to replace this sound for all new alarms. As I have no option to make this through some config file, so I add some file to the mentioned folder, for example, alarm.ogg (I made a copy of glass.ogg in the same folder for the sake of simplicity).
Nevertheless, when I create a new alarm, bark.ogg is still selected and my alarm.ogg is the last one in the list. Why does this bark.ogg file has some precedence over the one with higher position in the alphabet?
How can I change my default sound file for the new alarm?

Here glass.ogg appears first, I agree we should have a predictable result here so we can change the default sound for new alarms.
