I'm using music from the asset bundle provided by Scirra with the purchase of Construct 2. I'm inserting MattOglseby - 1 for the background music. I have it set preload and play on the start of layout (I've tried not preloading with no luck also). The music plays fine when I preview the game but once I publish the music doesn't play at all in Firefox, Chrome or IE. All other sound effects (non-music) work fine.
