Safari sound doesn't work

Safari mobile sound doesn't work when a game is hosted in my website, but it works well in Preview on LAN with the initial touch event trick.Someone have the same issue?I have the same problem with all the games i tested including Space blaster touch.

Overcoming iOS HTML5 audio limitations

Please someone who have an iPad with iOS 6 just tell me if the sound works when a game hosted in a website or not.All the audio play well when i preview on LAN but the same game when exported doesn't work anymore even space blaster.I have all the settings on, from volume to sound effects in iPad.I would be grateful because i am digging into this all day.

Thanks.

Have you set the right MIME type for .m4a files on your server? Otherwise the browser won't load them.

Thanks Ashley i added ogg and forgot m4a. shame.I never thought it was the mime type because i couldn't ear the sound in iPad as well in space blaster www/scirra/labs/sbmobileweb3/
