I am having a problem with a small microphone which creates tremendous feedback if I have the speakers on at the same time the mic is connected.
This is a little Creative Labs microphone about the size of a half-dollar coin. The sound card is a SB Audigy/ 5.1 Live. The speaker set is Altec-Lansing with a woofer.
I've used this microphone before and never had this problem. I've tried to balance the input with the volume settings for the sound card. No success. I either have no input from the mic or the speakers scream.
