Unable to set new alert sound default

[Wise Melon]

I am running Ubuntu Gnome 15.04 (with Gnome Shell) with Gnome 3.14. And I currently have the default alert sound "Drip", however I wanted to change to "Sonar", so I went into "Settings > Sound > Sound effects", and I tried just selecting the new sound I wanted and then closing the window. That did not work so I tried going back and doubling-clicking, right-clicking, etc... Nothing worked though...

I then tried it the command-line way, so I ran:

    gsettings get org.gnome.desktop.sound theme-name

Which outputted:

    'freedesktop'

So I then ran:

    gsettings set org.gnome.desktop.sound theme-name 'sonar'

And checked that:

    gsettings get org.gnome.desktop.sound theme-name

Outputted:

    'Sonar'

And it did, but still, no change, still the "Drip" sound...

Sound theme should actually be __custom, and it get created in ~/.local/share/sounds/__custom (once you modify settings)

There you should find symlinks pointing the alert you selected.

test alert is actually set with:
canberra-gtk-play -i bell-window-system

its possible though the some apps are using a different sound for alerts, what apps/alerts does this affect?

The contents of that folder is:

    bell-terminal.ogg bell-window-system.ogg index.theme

The command does produce the bell noise, it appears to do that noise on all of my applications. So how do I change it to Sonar?

I am sorry, I fixed my problem, it turns out that you have to click, then close the window, and then reboot before you do anything else to trigger the old noise. Then it works fine.
