Amnesia: MFP has no sound at all!!!

[plutomaniac]

The file works perfectly fine, download it from another browser and use a proper tool such as WinRar (or even the windows zip viewer) in case you are using something rare.

As far as the other problem is concerned, there is something wrong with your sound configuration at Windows if changing output does not work. Maybe old sound drivers causing problems, maybe the current creative card causing issues, maybe you need to install logitech software, maybe OpenAL is not installed properly, maybe windows default sound device is configured wrongly etc... You have to look this on your own first, it is not a problem of the game itself but rather a specific computer hardware or operating system configuration issue.
