I have a problem with multiple audio files on Android device. In a page I have a sound playing, a background audio on load event (but not a "soundtrack"), after the sound is started, different objects enter the scene, every object has an audio on touch-down event. When I touch one object, the sound on the object plays but the background audio is interrupted. It seems that multiple audio at the same time doesn't work on Android device. Can you help on this? Is there a way to fix?
