No Sound (Win 8.1)

[Refixul]

As simple as the title suggests, there's absolutely no sound in game.

The fact is I resolved many bug in this days, mainly checking files with the laucher and replacing them.
But I've also moved both OpelAl64.dll and OpenAl32.dll in Windows/System32 folder, solving the looping sound problem.
Could it be that to determine the no sound problem?

If you have a 64bit system, you might wanna try to copy those .dll's into the .\Windows\SysWOW64 directory
