Opera 23 is the one I downloaded.

I just installed Opera 2 days ago and I love it. I only have one problem. I play a lot of Facebook games and one of them has no sound with this browser. Does any one know how to get this fixed???? I sent a report but nothing have been fixed.This is the link to the game that has no sound,,,,,,https://apps.facebook.com/megafamecasino/?fb_source=bookmark&ref=bookmarks&count=19&fb_bmpos=2_19
