Can not find cd to install mic

Microphones do not require software or drivers to operate.

First, double click on the volume icon located in the system tray. If you do not see the volume control for Mic, then you will need to make it show up by going to Options --> Properties --> Check the box labeled Microphone --> Click Ok. You should now be able to see the volume control for the Mic. Make sure that this is not muted and the sound is turned up.

Second, you must have a sound card installed in your computer that supports microphones. Please check with your cards manufacturer or PC manufacturer to make sure.

Ok! I did everything u said back there but it still doesn't work, when i'm goingto test it in control panel or on windows live messenger imediately comes to mute.
