I created a pretty simple project: Just one sprite on the layout and one music file. On the start of the layout the music starts.
I can hear the music in Firefox, and Chrome, but if I export it to Awesomium, there is no sound. I have the latest stable browsers and the latest drivers for my PC.
I'm having the exact same problem. When I export my project to Awesomium, none of my music or sounds play.
