Music not play on mobile Safari about gdx-backends HOT 2 OPEN

Generally, playing music on game start is problematic on html5. Chrome and Firefox allow this if the user visited the webpage regularly, but you can't rely on it. That's why you should not play music on your start screen.

I gave it a try. On my Mac Safari, music never started on game start, but it worked when played a little later.
On my iOS 13.6 iPad, it did not play at all at first. I needed to set up debugging to investigate it, for this I needed to update the GWT plug in as well... and then the problem disappeared and music worked when played after a user interaction.
On my iOS 12 iPhone, music did play when tried some SECONDs after the game startet.
All in all, behaviour on Safari is weird and different on every device I used. I have no more ideas what to try.
Code trying to do this all automatically is here:

Do you start the background music immediately or after first user interaction?
