No sound in game uploaded to server

I've made a game and the event sound works perfectly in the preview and in others devices by wifi. But when I upload it to the server where is my website, the game works but with no sound. I've read that this problem could be incorrect MIME types server, but I don't know how to resolve it .

Thanks for your help.

Solved. Finally the problem is solved from the website control panel server by adding the MIME types: ogg as audio/ogg and m4a as audio/m4a.

I am having the same problem, so I added the 2 MIME types to the server and I still get no sound in IE. It works fine when I run it from my pc, but not when I upload it to the server.

I have ogg and alos m4a but still now sound after generate apk........... its been 1 month now.. still can't find solution... anyone?
