loadSound getting error: 'AudioContext error at decodeAudioData'

_spaces

Hi there, I'm getting an error trying to load a soundfile in p5 that I can't seem to find any documentation for. The error I get is "AudioContext error at decodeAudioData for soundtrack.mp3\n The error stack trace includes: \ndecodeAudioData\n at setup (localhost:3000/sketch.js:9:15)". The mp3 file is in the sketch directory, and everything else seems to be in order, can anyone shed any light on this?

var weather;
var ball = {};
var soundFile;

function setup() {
  createCanvas(200, 200);
  loadJSON('http://api.openweathermap.org/data/2.5/weather?q=London,uk&appid=9e063e3eb21fd879e4bf07c87e384bcb', gotData);
  soundFormats('ogg', 'mp3');
  soundFile = loadSound('soundtrack.mp3');

}
function gotData(data) {
  //print(data);
  weather = data;
}

function draw() {
  background(0);
  fill(255);
  if (weather) {
  ellipse(30, 40, (weather.wind.speed *4), (weather.wind.speed *4));
  fill (255, 0, 0);
  text('speed:' + ' ' + weather.wind.speed, 80, 140);
  text('direction:' + ' ' + weather.wind.deg, 80, 160)
  }
}

I am getting the exact same, and my canvas is barebones. Quite literally just the sound file, and playing it at the moment. Could someone chime in if you're getting this too?
