FloatControl volumeControl = (FloatControl) masterLine.getControl (FloatControl.Type.VOLUME); Getting the "Master Line " object is, at best, platform-dependant. You will have to list the Mixer s and the Line s at runtime using the AudioSystem static methods in order to determine which line you want. It can also happen that the master line will ...
