[SDL_mixer 2.0.0] No sound from iPad speakers

Hello everyone.

Last week I tried to use SDL_mixer on iPad to play a simple OGG file. The code compile, it works properly on Android and Windows, and I have no error when I launch the app on iPad, but no sound comes out of the speakers.

Later, I figured out that I could hear the sound by connecting an headphone, but I don’t understand why the sound is not played on the speakers when we don’t connect any headphone.

Do you have any idea why?

PS: I tried with another application like Chrome, and sound works and is played on speakers.
