Some browsers require users to startAudioContext with a user gesture, such as touchStarted in the example below.

Examples

 function draw() {
   background(255);
   textAlign(CENTER);

   if (getAudioContext().state !== 'running') {
     text('click to start audio', width/2, height/2);
   } else {
     text('audio is enabled', width/2, height/2);
   }
 }

 function touchStarted() {
   if (getAudioContext().state !== 'running') {
     getAudioContext().resume();
   }
   var synth = new p5.MonoSynth();
   synth.play('A4', 0.5, 0, 0.2);
 }
