i cant find the answer to my problem in the creative site ....
my problem is that my microphone use to work perfectly yesterday and today my microphone deactivate it self and then re-activate it self but starts doing a buzz sound ... and when i try to talk it makes my voice buzzy too
I assumes you have one of the X-Fi cards from Creative then.
First ensure you're all patched up.
Try changing Audio modes, sometimes changing that kicks things back into life.
Try setting the mode you're using back to default settings.
Do you have one of the cards with the break-out box? - If so try changing where your mic is plugged in and see if that makes a difference.
Tried the obvious "reboot fixes most things" trick?
