Audio works on web but not iOS

Hi there

We are seeing the following errors when calling play()

   Audio cache entry missing: music1
   ...
   TypeError: undefined is not an object (evaluating 'this.currentConfig.seek=0')

We are using

  "@capacitor/ios": "^1.1.1",
  "phaser": "^3.19.0"

And we have this scene

  preload() {
      console.log("musicOn assets/audio/example3.wav")
        this.load.audio('music1', 'assets/audio/example3.wav');
        this.load.on('fileprogress', function (file) {
          console.log("fileprogress file="+file.key);
         }, this);

         // remove progress bar when complete
        this.load.on('complete', function () {
          console.log("loading complete")
        }, this);
   }

   create() {
      console.log("audio1")
      this.music1 = this.sound.add('music1');
      this.music1.play();
   }

This works fine on the browser. But when running it on the iOS device and simulator, I am seeing these errors

** [log] - musicOn assets/audio/example3.wav
** [log] - fileprogress file=music1
** [log] - loading complete
** [log] - audio1
** [warn] - Audio cache entry missing: music1
** [error] - ...
** ------ STARTUP JS ERROR ------
** TypeError: undefined is not an object (evaluating 'this.currentConfig.seek=0')
..

We tried different format mp3, ogg, m4a, wav. Nothing works.
Anyone knows what this could be? thanks

I got it working. I needed to add the following in game.js

  audio: {
    disableWebAudio: true
  },
