To make an h5 mini-game, you need to long press and release the button to play a sound effect

GameStart.addEventListener('touchend', function(event) {
    event.preventDefault();
    Audio.play();
}, false);

The mechanism of IOS must be manually triggered by the user, but this should be considered correct for me, right?
I don’t understand very much, but it can be played normally with touchstart. I hope someone can explain it,
or something else The solution can solve my need.
Long press the button and release it before playing the sound effect
