+ * \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
+ * full volume and ignore the user setting. After it \sa Sound::isFinished
+ * you would turn the volume back to the user preference.
+ * 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!
+ *
+ * \code
+ * static Sound snd("alarm");
+ * if(!snd.isFinished())
+ *    return;
+ *
+ * changeMixerForAlarm( my_channel, "/dev/mixer", &snd );
+ * snd.play()
+ * \endcode
+ * 
+ * 
+ *
+ * @param mixer The mixer number/channel to use
+ * @param file  The file name. If you convert from QString use QFile::encodeName
+ * @param snd   The sound to wait for finishing
