Headset Isn't Working Right And It Isn't Faulty

[dazuk1972]

I have a good headset that has worked fine for ages. Now it's not working properly. When I plug it in I can hear a quiet hissding in the ear pieces and I can hear myself breathing through the ear pices and when I talk I can hear my voice coming through the ear pieces as if I'm somebody else talking to me. When I record my voice I either hear myself very quietly or not at all. Why doesn't my microphone work for recordings and voice chats and why does it work perfectly to make my voice come through the ear pieces when I'm not supposed to hear my voice coming through the ear pieces? My microphone does work but the sound is going the wrong way, it's going through to the ear pieces and not through anyone else's and not in any recordings. What do I do to fix this? Also I use Windows 7.

Many thanks.
