Just a couple of day ago I plugged my microphone in to my computer and it was working fine, now it just seems to make a consistent buzzing noise every time it is plugged in. I know it is not something with the headphones because when I am talking with someone on Skype I can't hear the noise. Is there any simple way to try and fix this problem, or could it be something to do with the sound card all together? Also, is there any mixer program that is better than the one that comes with vista? Preferably one that gives the option to lower certain frequencies, because I originally thought I could use something like that to try and reduce the buzzing noise. Thanks.
