Okay, I think I have it figured out. When it comes to gaming, virtual surround sound is incompatible with certain API's. API's control the audio that we hear. Stereo sound is always compatible, so for certain games, I will be stuck with only stereo. However, my particular headset, is surround sound compatible with most games, there are just a few that I'm stuck with stereo on. From what I've read, any game that uses openAL, can only use stereo.
So this is my question, does amnesia use OpenAL? Because I read this:

And that makes me think they use OpenAL, but I'm not sure. I now know that openAL stands for open audio library, thanks to the person above me. However, I'm still confused as to exactly what it does, or if amnesia uses it.
