Whenever I run my hand over the microphone it makes a squeaking noise…also when I turn up the volume fairly high. I can hear my songs fine it just gets very irritating.

Here’s what you can try. Enter the advanced sound and audio devices properties in the control panel and adjust the microphone settings. You can lower the microphone volume level or mute the microphone at all.

I have a Toshiba Tecra A3. I recently took off Windows and reinstalled it, but now I’m having problems with my USB webcam and microphone. The video is fine, just that i can not record any sound….HELP! I downloaded the CD it came with fine, and reinstalled the audio driver…nothing seems to work. How can i fix this?!

Maybe the microphone does not work because it’s muted?
Here’s what you can try.
Go to the Control Panel and click on the Sounds and Audio Devices icon. Click on the Advanced button. After that click on the Properties in the Options. Enable Microphone volume control and click OK. Now you should have the Microphone volume control in the Play Control window. Make sure the microphone is not muted.
Uncheck the Mute box and test the laptop again.
