sound pixi Sound complete() Event not working

[dazzafact]

 does anyone know why this Code section does not trigger on the "complete" event? Everything else works smoothly. Also I do not get any error. Using PixiJs v5. sound v4
 

	$vm.sound = PIXI.sound.Sound.from(audio);
		$vm.sound.volume = 1;
		$vm.sound.autoPlay = true;

		$vm.sound.complete = () => {
		console.log('endsAudio00 1',1);

		$vm.joins = PIXI.sound.Sound.from({
		url: resources['joins'],
		volume: 1,
				});

			};
