Is it a known issue that the Audio/Video controls don't appear to be working on the EVO stock browser (and also I'm assuming the same crapware browser built into all HTC Sense UI phones)? or should I be using something other than:

Code:
new Ext.Audio({
                id: 'audioPlayer0',
                dock: 'bottom',
                cls: 'audioPlayer',
                url: 'audio/page1.mp3'
            })
