Not worked html5 audio

Hello all!
The first issue - if i use webAudio, all audio files is working except on Iphone (all products apple). On ios all sounds not working.
(i’m load mp3 and m4a)

I’m find solution - use html5 audio:

on main file in config i add

audio: {
		disableWebAudio: true
},

on class scene i add :

this.sound.pauseOnBlur = false;

this.touch = this.sound.add('touch');

this.touch.play();

After add that settings - audio doesn’t work anywhere.

I am get all code for this example - Phaser 3 Examples

I create new file on my PC, save code for that example - audio doesn’t work anywhere.

What am I doing wrong?

I’ll update my post, you’ve been busy today the situation has changed a bit:
**
I changed the way the sound starts - removed the automatic start, added the start of the sound on a click event on the screen.
Thanks to this action, the sounds began to be played on the computer.
But on any mobile devices, the sound still does not work.
**
On a computer, when you click on the screen, an audio object is created in the HTML5AudioSound object with a large number of methods and properties.
When clicking on the browser screen on a mobile device(start code - this.touch.play()) , nothing is created in the HTML5AudioSound object in the audio object.

Surely someone faced such a problem, tell me why there are no sounds in mobile browsers.
