Remarks
The lock manipulated by these functions protects the callback function. During an SDL_LockAudio()/SDL_UnlockAudio() pair you can be guaranteed that the callback function for the default audio device is not running.
SDL_LockAudio() is not a re-entrant function and can potentially block if it is called more than once from the same thread before a call to SDL_Unlock() is made.
Do not call these from the callback function or you will cause deadlock.
