* \brief Change the Volume for the Alarm and set it back after playing is finished

* If you play an Alarm Sound you might want to change the Mixer to

* The problem is that we used to enter the event loop while waiting
* for the sound to be finished triggering all kind of reentrance
* problems what a library shouldn't introduce.
* Instead of manually waiting for the sound to be finished use
* this Method and it will automatically restore the Mixer to
* the user configuration after the sound finished playing.
*
* Note: The onwership of \param snd is not transfered and playing
* is not started in this method. If 'snd' gets deleted before
* playing is finished the volume doesn't get set back to
* the user preference!
