Jevins Wheel Sound

in the winwheel.js file (most likely called winwheel_1.2.js) in the function startSpin(determinedValue) (around line 130) you want
to add following code right below "var stopAngle = undefined;"

//

var Wheelsound = new Audio('youraudiofile.mp3');
Wheelsound.play();

//
the sound file should be in the same directory as the js file

that worked for me and should also work for you :) good luck with the wheel.
