Visual que if sound is Off or On

Hello,

We have had success using on/off volume using JavaScript code from the discussion link below.

Is there a way to link an icon for visual purposes to reflect if the volume is currently on or off?  Perhaps show the icon as red if volume set to off ?

Thank you
