Hi

I am trying to get a simple sound out of this framework, but am absolutely out of luck. Been searching all over the place. It shows the audio player and I get to press the play button, but no sound. Anyone know why? I test in chrome.

This is my code:

Code:
Ext.setup({
    tabletStartupScreen: 'tablet_startup.png',
    phoneStartupScreen: 'phone_startup.png',
    icon: 'icon.png',
    glossOnIcon: false,
    onReady: function () {
        var browseCarousel = new Ext.Carousel({
            requires: [Ext.Audio],
            defaults: {
                cls: 'card'
            },
            items: [{
                html: 'A'
            }, 
            {
                 xtype: 'audio',
                 url: 'baby_laugh.mp3'                
            },
            {
                html: 'B'            }
            ]
        });
        new Ext.Panel({
            fullscreen: true,
            layout: {
                type: 'vbox',
                align: 'stretch'
            },
            defaults: {
                flex: 1
            },
            items: [browseCarousel],
            dockedItems: [{
                xtype: 'toolbar',
                title: 'This is the toolbar',
                dock: 'top',
                ui: 'light',
                items: [
                {
                    text: 'Home',
                    ui: 'back',
                    handler: function () {
                        main.setCard(0);
                    }
                }]
            }]
        });
    }
});
