Kako zagnati wav datoteko [Java]

AudioInputStream  AIS =   AudioSystem.getAudioInputStream(new File("source/store.wav"));           
            AudioFormat format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
                   AudioSystem.NOT_SPECIFIED,
                   16, 2, 4,
                   AudioSystem.NOT_SPECIFIED, true);
            DataLine.Info info = new DataLine.Info(Clip.class, format);
             Clip clip = (Clip) AudioSystem.getLine(info);
            clip.open(AIS);
            clip.start();

Kodo mi prevede, ne javi nobene napake ali opozorila, toda zvoka pa ni. Java je pa 1.6.
Kaj je narobe?
