I'm currently developing a videogame using CocosSharp. I'm using the CCAudioEngine to play both background music and sound effects. In the Android device I'm using to develop, everything works fine, but after running it in another Android phone, the sound effects don't work. Why is this happening? Is it the audio format? I'm using .WAV for the sound effects.
I also decided to test something simpler, so I downloaded CCAudioEngineSample and ran it with no modifications. Still, one device plays it and the other one is mute.
The device this is not working on is a HTC One M9, running Android 6.0.
