Well performance wise the Audio Element works much better. But that element seems to have an issue on iOS, that the volume property has no effect. On Android and mac it works fine…
And apart of that, if I wanted to publish the game, I would have to put the qml code into the resources, to kinda protect my intellectual property, and deliver my audio content unprotected, as a folder in the bundle, right? Do you have experience in getting that through the app store gates?
