Hi!
I'm trying to play audio files from web application and can't get audio to work properly. 
There is always some kind of lowered volume involved even when phone volume is cranked up to 100%. Changing volume on device turns up overall volume a bit, but that is not near the loudest it can get. 
Behaviour is explained with more detials below:

simple example source code:

<audio id="notification" controls>
    <source src="~/sounds/notification.wav" />
</audio>

I have tried this on 3 different models:
- iPhone X (iOS 13.7) - audio starts with low volume (probably 10-20%), after pausing and playing again sound restores volumne to selected level (let's say 100%)
- iPhone 12 Pro Max (iOS 15.4) - audio have lower volume all the time, except when you go to iPhone Music player and turn the volume up
- iPhone 13 (iOS 15.3.1) - same as iPhone 12
Iphone 12 and 13 have similar bug after, when you finally set the volume and lock your phone then the volume slider is not working (occasionally).
Anyone experiencing something similar?

Thanks in advance!
