Trying something new and different. I've had problems with this for a long time and just gave up on it. Now I really want to fix it since you guys are the bomb when it comes to helping other. I have a logitech Microphone Pro 4000. I remember it used to work very well, but now it's so bad anyone on the receiving end say's shut that @#$% off! My mic works off the built-in mb port. Realtek AC97 Audio is the driver. I just tested it and it work fine for me but why would it act corrupted for someone on the other end? Let me know if you need any other info to assist in this much need resolve.
