When audio is added to a game project with r97, and previewed in Safari for Windows browser I get this JavaScript error, and then a blank screen.

I get the same results previewing in Safari browser with an exported project.
When I remove the audio object the game runs perfect but no audio then.
This can be reproduced by previewing the Space Blaster game in your examples folder, or any game that uses the audio object, with the Safari for Windows browser.
