Headset Mic & Sounds Playing At The Same Time?

My Speakers and Internal Speakers along with the Microphones are screwing up.This problem only started today, I haven't got a clue why and I haven't changed any settings whatsoever, Everything was working fine until one moment they weren't.I've gone into Sound to try and fix the issue, I set my Sounds as Default for the headset, and I still have them playing through both, and I did the same for the Microphone, only on that one.In Playback Devices, Speakers / Headphones is one and Communication Headphones is another, even if I disable the first, I can't get the second as Default for both, it won't let me have Default Device for only the Communication Headphones.Under Recordcing it's much the same issue except the first one is Internal Mic, it's allowed me to put the Microphone / Line In as Default, except it won't pick up sounds from the Mic, only the Internal Mic even if it's not enabled.
