How to pause a song? Musical Addon

Only with the purpose of learn, I made this script that allows you listen to a music while working in Blender. Cool


import bpy
import aud


class ManoMusicPanel(bpy.types.Panel):
    """Creates a Panel in the scene context of the properties editor"""
    bl_space_type = "VIEW_3D"
    bl_region_type = "TOOLS"
    bl_category = "Mano-Addons"
    bl_label = "Music"


    def draw(self, context):
        layout = self.layout
        row = layout.row()
        col = layout.column()
        col.prop(context.scene, 'conf_path')
        TheCol = layout.column(align = True)
        TheCol.operator("sound.mano_play_music", icon="PLAY")
        TheCol.operator("sound.mano_pause_music", icon="PAUSE")


class ManoMusicPlayOperator(bpy.types.Operator):
    bl_idname = "sound.mano_play_music"
    bl_label = "Play"
    bl_options = {'REGISTER', 'UNDO'}
    
    def execute(self, context):
        device = aud.device()
        path = context.scene.conf_path
        
        # load sound file (it can be a video file with audio)
        factory = aud.Factory(path)
        global handle
        # play the audio, this return a handle to control play/pause
        handle = device.play(factory)
        
        return {'FINISHED'}


class ManoMusicPauseOperator(bpy.types.Operator):
    bl_idname = "sound.mano_pause_music"
    bl_label = "Pause"
    bl_options = {'REGISTER', 'UNDO'}


    def execute(self, context):
        # stop the sounds (otherwise they play until their ends)
        #handle.pause() #Does not work!!!!!!!!!
        handle.stop()
        
        return {'FINISHED'}


def register():
    bpy.utils.register_class(ManoMusicPanel)
    bpy.utils.register_class(ManoMusicPlayOperator)
    bpy.utils.register_class(ManoMusicPauseOperator)
    bpy.types.Scene.conf_path = bpy.props.StringProperty \
      (
      name = "Root Path",
      default = "*.mp3",
      description = "Define the root path of the project",
      subtype = 'FILE_PATH'
      )


def unregister():
    bpy.utils.unregister_class(ManoMusicPanel)
    bpy.utils.unregister_class(ManoMusicPlayOperator)
    bpy.utils.unregister_class(ManoMusicPauseOperator)
    del bpy.types.Scene.conf_path




if __name__ == "__main__":
    register()

So,
How to pause? I only know how to stop.
I also didn’t like having used globals in this case.
