Windows 8 64bit

Hello
I've downloaded the game and I'm trying to run it on Windows 8 Pro 64bit.
At the beginning I found a problem with openal32.dll, it just didn't exists. So I've downloaded one from Internet. It works, or rather the configuration works. But combobox with sound device is empty. I can open it but it's empty, I can see about 3 empty lines in drop-down menu inside combobox.
When I try to run the game (with administrator privileges, with Windows XP compatibility mode) it crashes with an error message:
Reflect assert!
Reflect Assert Box
----
Cond: FALSE
Message: Failed to open audio device
In file: .\cSoundManager.cpp, at line: 456
And it quits after that.
I suppose it's because I don't see any sound device in configuration window. But I have enabled and working sound device. It works fine in all other applications and games.
What can I do with it?
Thank you
