Website sometimes unable to load. Preload() sound file issue

p5.js Libraries
1

I’ve made a website with a sketch that utilizes the preload() function to load a sound file. When one visits the website for the first time, it gets stuck loading. If you open the console through developer tools you see the message

p5.sound.min.js:24 Unable to load crash.mp3. The request status was: 206 ()
 The error stack trace includes: 
loadSound
    at preload (https://nhsegal.github.io/Bowling-Ball-Activity/sketch.js:15:16)

If you then reload the page, it works fine. How can I have it load correctly the first time?
Here is the website.
