Hi there. Update to the new iOS 14.0.1, and mp3 sounds in any BabylonJS program no longer works in any browser. This is a serious issue!
Pinging @cedric 
Just want to clarify, this time includes Chrome browser…even that gives no sound
It’s my understanding that browser choice on iOS is an illusion.
They are all equally inhibited.
they are both the same. Chrome on iOS is just a facade on webkit
Not sure if you’ve already found a solution, but I’ve noticed that with iOS 14.2 if the ringer is silenced the audio will not play even if I click the “sound” button that pops up in the browser. I haven’t tested on other phones/versions and the results seem intermittent. Hopefully this helps a little.
Edit: Additionally, I noticed the audio will not play if I’ve left the browser and then returned to the already open page.
