[FIXED] What does JavaFX use under the hood to play sound?

Issue

I had some problems with playing sound using JavaFX on my Mac, so I decided to dig a little. I've found class called OSXMediaPlayer, with method that has the following signature:

private native void osxPlay() throws MediaException;

and - unfortunately - an empty body. Does that mean that Java call OSX command under the hood? Can I open a terminal and try it myself?

Solution

It does not call a command line program. It calls the native macOS audio APIs CoreAudio or AVFoundation.

Can I open a terminal and try it myself?

No, because the terminal only lets you access command line programs, not APIs.
