Windows XP Microphone Settings
What to do if your problem STILL isn’t solved!!
Check that your microphone isn’t muted (sometimes there’s a mute button on the microphone itself or on its cord),
Check that the mic is connected to the socket, and try disconnecting it and connecting it again.
Check that you can hear other sounds! Maybe it was the sound playback made you think that the mic isn’t working! You can try our sound test page for that.
