RE: Recording Audio Problem Dell Insipiron 14z (5423)
Windows has a native driver for the webcam so you don't need to download and install one.
Your screen shot shows that Windows is recognizing Microphone Array, so that looks right.
It all looks okay to me, but it is always possible that software is not configured correctly somewhere. The best thing would be if you could restore the laptop back to the original factory configuration using the restore image on the hard drive, but if you have wiped the entire hard drive then the image was wiped too.
