**to reproduce** prepare an mp3 called `sound.mp3`, 10 seconds long. Use the following sketch: ``` import processing.sound.*; SoundFile sound; void setup() { sound = new SoundFile(this, "sound.mp3"); sound.loop(); } void draw() { background(255); } void mousePressed() { // sound.stop(); // does not help the problem sound.jump(0); } ``` Run, wait until the sound starts to play. Click the mouse, observe what happens. Wait a few seconds and click the mouse again, observe what happens. **expected behaviour:** with every mouse click, the sound restarts at the start of the song. **actual behaviour:** - The first mouse click restarts the sound. - Subsequent mouse clicks trigger a new instance of the sound, while older instances continue to play.
