So I now know that it's google preventing my sound, and that if I click the browser with my mouse, I get the sound to play.
So now I have two issues: 1) I cannot figure out how to make the sound work, even looking at examples like Kiwi Story.
2) I have no idea how to change the preview browser to Firefox.
If anybody has a tutorial, or instructions on how to actually make sound play in Chrome, I would greatly appreciate it. Or at least a clue!
Really sorry to trouble others for this, but I just spent the whole night trying to figure this out, and those are many hours that I could have been working on my game, which I can't get back.
Thanks in advance again, to any who have a moment to help a clueless newber!
