I think there's a problem with my copy of MW2. It's to do with the sound on it. Example: if I were to throw a flashbang to my character's left, it sounds nice and loud when it explodes. If I throw it to the character's right, however, it sounds like it's coming from the end of a tunnel. Same with AI voices, etc. It doesn't affect my playing, but it's very annoying. Does anyone know what the problem is, and is there a way to fix it? Cheers.
