So the sound (voices/sound effects) works fine, until I talk to someone and it zooms in on their face when this happens the dialogue sound cuts off. This happens in every instance of 1 on 1 dialogue. I have seen a few posts of people with this problem, but no solution.

Check in your sound card tools/control panel that your outputs match the speaker configuration you actually have.

Yes, this happens if your settings are for a surround mode, when you don't have the actual speakers. The dialog is sent to the center speaker in surround mode.

Sweet, thx for the tip i'll try that right now

Worked like a charm. I went to my sound options and opened the 'speakers' tab, it was set on surround sound like you suggested it might be. i changed the configuration to 'stereo' problem solved.
