`loadSound` Callbacks Not Triggering

[SableRaf]

The loadSound() function's callbacks (success, error, and whileLoading) aren't being triggered as expected in the p5.sound prerelease. This prevents handling events during the loading process and confirming a successful or failed load.

Function Signature

loadSound(path, [successCallback], [errorCallback], [whileLoading])

Example

let player;

function preload() {
  player = loadSound(
    'https://tonejs.github.io/audio/berklee/gong_1.mp3', 
    () => { console.log("success"); }, // Success callback
    () => { console.log("failure"); },  // Error callback
    (progress) => { console.log(`Loading: ${progress * 100}%`); }  // While loading callback
    );
}

function setup() {
  createCanvas(100, 100);
  background(220);
}

function mousePressed() {
  player.play();
}

Expected Behavior

• The whileLoading callback should print the loading progress percentage.
• The callback should print "success" to the console when the sound is loaded.

Actual Behavior

• The whileLoading callback isn't triggered, and loading progress isn't shown.
• The callback isn't triggered, and "success" isn't printed.

@tmartinez88 this._decrementPreload() needs to be manually called when loading completes for preload() to work with loadSound(). See docs here
