Internal microphones not working

I am using a Dell Latitude E5520 laptop but the laptop doesn't recognise that it has internal microphones!!
I've googled the problem and have downloaded drivers from Rwealtek etc but to no avail.
I've included a screenshot of the recording devices tab which only shows unplugged microphones.

I'd welcome any advice please

Hi and welcome to Seven Forums!

I know you have said that you have tried it, now please give it one more chance and if it fails to work we will dig deeper to try to solve the problem.
After accpeting the terms you need to download the first driver from any of the 3 servers on the right.

I've re-loaded the Realtek audio drivers and nothing has changed I'm afraid, might have to accept that the built in microphones aren't going to work after all.

issy1, just reinstall the audio driver and it might work. I've experienced the same problem and after I've installed the latest audio driver from DELL website, it worked.

Windows 7 32
Drivers are here


I can confirm the DELL Latitude E5520 has well integrated microphone.
Just got the same problem with Skype and used the drivers available for download from DELL website:

Google the name of the driver and you should easily get it.

INstall software.
Then go to your peripheral manager.
Click on the audio controler and choose the "update drivers", then point to the directory created by the executable.


Hope it helps.
