声音功能在TouchEvent上不起作用

如何解决声音功能在TouchEvent上不起作用

当我尝试向TouchEvent Function添加声音时，该声音在Android模拟器上不起作用。但是，如果将TouchEvent替换为MouseEvent并在Adobe Animate上对其进行测试，则效果很好。我在做什么错了？

Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
var mysound: ClickTap = new ClickTap();
var mySprite: Sprite = new Sprite();
var myTextField: TextField = new TextField();
mySprite.graphics.beginFill(0x336699);
mySprite.graphics.drawRect(0,40,40);
addChild(mySprite);
mySprite.addEventListener(TouchEvent.TOUCH_TAP,taphandler);

function taphandler(evt: TouchEvent): void {

    mysound.play();
    myTextField.text = "I've been tapped";
    myTextField.y = 50;
    addChild(myTextField);
