FATAL ERROR: No sound devices available! Check your OpenAL installation

[tappi]

I have the same problem and I can't find a solution for it.

The game gives the error 'FATAL ERROR: Failed! Check your OpenAL installation'.

I don't have a game settings file in the amnesia folder in my documents, only the log file.

I installed the openal sdk mentioned in this thread and tried the examples, and they worked.

I'm running a windows vista 64-bit, my speakers are connected through the SPDIF interface, but the problem persists even if i connect my headphones and change the default output device to the normal 'speakers' interface through the windows playback devices dialog.

Any help?
