If you have tried construct2 preview over wifi feature, and it fails when running the app in chrome browser on the tablet, then there is not much we can do to make it work. If it works in chrome, but not crosswalk, then crosswalk team can investigate.
You might be able to have your game check the tablet it is running on and disable sounds. The javascript part of this is simple, but I don't know how to do it in construct2.
