Have you preload the audio on start of the layout (or anywhere before you 'play' the music) ?
If you haven't, then follow this:
1. Make sure you've preload it on Project Properties:
2. Preload your Music on start of a layout (Usually i put it on splashscreen layout)
3. Play it on wherever you want to play it
Don't forget to look up the problem with Phonegap: https://www.scirra.com/tutorials/283/ph ... ency-audio
I would recommend you to use XDK Crosswalk
