How do I get sound working on ios for HTML5 ?

Hi,

I have no sound on ios 8+ on a game i'm working on.
I've read that i should use first a "tap event".
I've done this but without success.
Any idea ?

Also, on ios 7+, the loader crash.
I've tested without webgl, it's the same.

This is the game :

No idea ?

I answer to myself :
For Internet Explorer and Safari mobile sound to work, you need a special .htaccess file.
I've found this in this forum.
Also, you'll need to clear the safari cache.

Now, my sound works.
