This is Intels answer in xdk forum
I tried your app you sent me. It looks like it is using Web Audio when you are running on the device. The audio is generally supported in webview but not reliable. You should be using Cordova for audio. If there is a way in C2 to force your app to use Cordova you should do that, otherwise you have to write js code to implement audio using Cordova plugin. There are examples available in sample apps.
So my ? what is wrong here .. since thought that C2 out of the box > Cordova export would work
If someone would try this simple capx. Export as Cordova in C2 for iOS
and build in XDK as Cordova .. and check for audio on device (iPad/Iphone)
Have a nice day
