After searching and wondering for the last 5 hours, with no help at all from this site (sorry)
I think I may of found my problem, but no solution.
Playback device.
My Mic works fine, part of my headset and I believe this is because there are sufficient playback devices to suit the microphone.
As for the speakers. There are not.
Any help would be appreciated on any sort of solution, or if this is really my problem.
