Sound detection completed in THREE.PositionalAudio?

Question

I want to determine when the sound ends, but all the examples that I found are not working.

// Create sound
var sound1 = new THREE.PositionalAudio( listener );
sound1.load( 'sounds/Example.ogg' );
sound1.setRefDistance( 30 );
sound1.autoplay = false;
sound1.setLoop(false);
mesh1.add( sound1 );

// Start sound
setTimeout(function() {
    sound1.play();
}, 2000);

// Try to detect end #1
sound1.onended = function() {
    console.log('sound1 ended #1');
};
// Try to detect end #1
sound1.addEventListener('ended', function() {
    console.log('sound1 ended #2');
});

Three.Audio- a wrapper around the sound object of the buffer source. https://github.com/mrdoob/three.js/blob/ddab1fda4fd1e21babf65aa454fc0fe15bfabc33/src/audio/Audio.js#L12

It seems like it overrides the onended event and binds it to its own function, so we just do the same:

sound1.source.onended = function() {
    console.log('sound1 ended');
    this.isPlaying = false; /* sets Three wrapper property correctly */
};

isPlaying = false, , , .
