Amnesia: MFP has no sound at all!!!

[assasin199127]

As, I mentioned I can't even extract file from archive it gives me strange error.
I will try the steps you showed and respond.

Update:
1. through I have verified and reinstalled game several times, when I verified now it was missing 79 files.
2. I managed only to find OpenAL 2.0.7 (closest to 2.1), interestingly there aren't many download places for it.
3. Changed name of folder Amnezia to Amnezia_Test
4. Still no sound only changes are in graphic.


p.s. I checked main_settings.cfg and the sound options are

"<Sound Device="0" Volume="1.000000" MaxChannels="64" StreamBuffers="8" StreamBufferSize="262144" />"

sound device="0" << maybe this is problem?
