Problem with Oculus tracking head and 3D sound

Hi all, I have a problem with the sound head tracking using Oculus. Everything works fine when using the mouse to move around, but when I use the oculus and I move my head around the sounds are just stuck on a fixed position as if the head was not moving at all, giving a completely unreal feeling of the sound environment. Does anybody know how I can fix this problem? I would really appreciate that somebody could help me to find a solution. Thanks in advance.
