Not really knowing what your 'everything else' is (that is what do you have hooked up to the D2X), but you should be aware that when using headphones, you are listening to your onboard audio, NOT your $200 D2X.. Using on-board audio input for mic is fine for things like skype or in-game chat, but I would look for a way to actually hook headphones to the D2X. If you are using high-end PC speakers, those almost always have a headphone jack on the control pod. If you are hooked to a HT receiver, I'd use the headphone jack on that.
