I have a project that works fine on desktop machines but on mobile especially iOS, sound is missing.
Now comes the strange part: Only music is missing but other effects and the speakers voice are playing like expected.
I'm using a plugin https://www.scirra.com/store/royalty-free-game-templates/advanced-audio-fade-driver-2302 to play the background music (Advanced Audio Fade Driver). Maybe it has something to do with that...
But even the plugin doesn't do any blackmagic. It just turns the volume up and down.
The sound files are imported as m4a and ogg with lowest quality.
Here is the link to the project:

You finde the game that isn't working next to the red curtain, the purple one.
