when the user wants to set a sound for a notification, it will not work.
Steps to Reproduce:
1. launch kcmshell5 kcmnotify
2. now set an notification sound for a specific action
3. try to preview this sound (or trigger the action)
no sound will be played
sound should be played
we found that if we replace the path to an sound file (for example)
with "file://" in front:
the preview works and the notification sound also works.
