Sound is 90 degrees off center

[oobaka]

I have my X-Box hooked up to my stereo.
All other X-Box games are perfect in regards to the sound.
Project Snowblind is off center.
When looking at a person talking to me the audio is all in the right channel.
If I turn 90 degrees right, the audio is centered.
It's not hooked up to any type of surround sound, just 2 speakers.
The same audio problem occurs when being fired upon.
It's very difficult to determine which direction the shots are coming from unless they hit me.
