How do I mute the microphone?

on most systems u can use the volume contol. (dubbelklick on volume icon in systemtray)
then: options--> properties-->recording
here u can select the sound input. if u select the line in, the micophone will be off.
hope this helps,

And if you want to mute the mic's output instead of its input you can try this registry edit where you alter the value of the registry subkey 'DisableMicFromPlayback' in Windows XP.


(This Registry edit was originally posted in a basic form by dilleyo, and jk79 later added more detailed instructions. I have put it into a step-by-step format for those of us who need it this way. If you are already familiar with editing the Registry skip down to the direct path at the bottom.)

1. Go to Start menu and click on Run. Type 'regedit' without quotes and click OK to open the Registry.
2. At the top of the list, highlight My Computer.
3. Under the Edit menu, select Find.
4. Type in 'DisableMicFromPlayback' without quotes and click 'find next'.
5. Highlight DisableMicFromPlayback. Right click on it and select Modify.
6. Highlight 01 and change to 00. Click OK.
7. Exit the Registry and restart the computer.

Next, configure the system mixer:
1. Open Volume Control by right clicking on the speaker icon on the taskbar, or go to Start/Control Panel/ Sound & Audio Devices Properties/Advanced (button).
2. Under the Options menu, select Properties.
3. Under show the following volume controls check the box next to Microphone. Click OK.
4. A mic control appears in the Volume Control. Check the mute box.

Here is the direct Registry path to the key:
