If your audio stops when closing FL Studio, or switching to another application, make sure that SETTINGS > AUDIO > 'Auto close' is selected (switch is ON).
If you are having playback issues and the sound not playing or your play position cursor is stuck, try enabling the 'Mix in buffer switch' option (Windows only).
If the issues persists, try switching to another Playback tracking method within the Audio Settings again (Driver or Hybrid).
