Mic problem. Gamecom 367 Plantronics headset and Realtek driver

I am having my Gamecom 367 headset. It started out fine. Then it got super quiet. Now its not recording at all unless I blow really hard into the mic opening directly, and even then its really soft. I think it might be a driver problem. I have Realtek driver, and I have had some registry problems with it in the past. When I go and look at the audio output master controls it lists "rear pink port" in the volume list (which is where I have it plugged in). When I go to input master controls, I can't change the settings and it doesn't seem to be connected to the headset. The headset seems to be of a good make so I don't think that its just breaking down. Any ideas? Did I provide enough info?



EDIT: I checked it on a friends computer. Same problem. So its not the driver. So am I right in assuming that its the fault of a hardware breakdown in the mic itself?

Its not. I am just sending it into them for warranty. Thanks though.
