I can’t seem to get the p5.sound.js to work correctly. The console error I keep getting is:  
p5.sound.js:819 The AudioContext was not allowed to start. It must be resumed (or created) after a user gesture on the page. [https://goo.gl/7K7WLu](https://goo.gl/7K7WLu)

I _think_ the user needs to interact with the page/canvas first before it is allowed to play audio.  
Just so that annoying pages don’t give un-expecting people heart attack by automatically playing audio 🙂

I tried that and got hit with this ☹

p5.sound.js:1883 Access to XMLHttpRequest at ‘file:///C:/Users/coled/Documents/Programming/p5js/bubble%20sort/sounds/laser.mp3’ from origin ‘null’ has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.

I’d suggest running a local server that normally solves some problems. Normally browsers don’t do great loading files directly from the filesystem. [http-server through npm](https://www.npmjs.com/package/http-server) is super simple or live-server there too. I think there’s one through python too that I’ve heard a lot of people use.

None the less that still might not fix this particular error you can read more about it [on the Mozilla docs](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS/Errors). And [here is how to disable CORS for testing](https://pointdeveloper.com/how-to-bypass-cors-errors-on-chrome-and-firefox-for-testing/).
