793/**
794 * \brief Change the Volume for the Alarm and set it back after playing is finished
795 *
796 * If you play an Alarm Sound you might want to change the Mixer to
797 * full volume and ignore the user setting. After it \sa Sound::isFinished
798 * you would turn the volume back to the user preference.
799 * The problem is that we used to enter the event loop while waiting
800 * for the sound to be finished triggering all kind of reentrance
801 * problems what a library shouldn't introduce.
802 * Instead of manually waiting for the sound to be finished use
803 * this Method and it will automatically restore the Mixer to
804 * the user configuration after the sound finished playing.
805 *
806 * Note: The onwership of \param snd is not transfered and playing
807 * is not started in this method. If 'snd' gets deleted before
808 * playing is finished the volume doesn't get set back to
809 * the user preference!
810 *
811 * \code
812 * static Sound snd("alarm");
813 * if(!snd.isFinished())
814 * return;
815 *
816 * changeMixerForAlarm( my_channel, "/dev/mixer", &snd );
817 * snd.play()
818 * \endcode
819 *
820 *
821 *
822 * @param mixer The mixer number/channel to use
823 * @param file The file name. If you convert from QString use QFile::encodeName
824 * @param snd The sound to wait for finishing
