built in microphone for Latitude E5510 not working

[anhpham]

I have problem with the built in mic for my brandnew laptop (3 weeks old), so don't think that it is a hardware problem. I tried to reinstalled everything but does not work. I was infected by a spyware, then install AVG and scan the system, but as soon as the spyware was removed, so was my mic.
Thanks for help.

Make sure you have all the required drivers installed for your system, you can get them from here

Sadly I tried what you have suggested . What Dell technical support said was I should reinstall the Windows 7. That sucks!
Let me know if you have other options.

THanks a lot
