I think the game is trying to playback as if I had a 6+ speaker setup, but I don't!

Eg, I can hear my own weapon just fine, and if you're in front - but I can't hear the guy shooting to my right. As well, the game sounds devoid of almost any ambient sound.

In the console, I found that the game had set my speaker count to 6! (I have a 2.0 system, and my sound card/windows is set as-such).

Forcing these to 2 did not appear to resolve the issue.

Has anyone else noticed this problem?
