Audio control

I’m trying to use the Audio control to play a sound as a notification.  The control is not visible.

As a test I wrote some code to play the file when you double click on a label.  It works – in chrome on Windows.

But I cannot get it to work in safari or chrome on mac.

Are there any known issues w/ the audio control to get it to play the audio on safari on mac?

Or is there a preferred way to do this?

Any advice would be great…

Thanks,

Matthew
