While you can apply sound effects to widgets individually using a widget's .tapSound, .dragSound, .releaseSound and .changeSound properties, you can use SetSounds() to globally set (or disable) sound effects for all widgets at once. Using this command will override the individual settings of any existing widgets and set the default values for the widgets you create at a later time.
Note: If you create any widgets after calling SetSound and specify individual sound properties for a widget, the individual widget settings are used then.
SetSounds (tapSound, releaseSound, changeSound, selectSound)
tapSoundID, releaseSoundID, changeSoundID ,selectSoundID
Sound ID to use (as defined in your theme's .lua settings file). To disable a sound, pass nil.
