my in built mic makes static noise
I recently got a Dell Lattitude E7440 for personal use, I wanted to use the inbuilt microphone to talk to friends but it makes a static noise and voice cannot even be faintly heard. I have searched for weeks and weeks and many solutions but none seem to work.

Update October 15, 2021 = After completing troubleshooting, a DELL-Cares agent setup a system exchange.

Hi azlan.13,
Which software are you using to check the mic functionality? Have you updated the BIOS firmware along with audio drivers if not you can download it from the given link https://www.dell.com/support/home/us/en/04/product-support/product/latitude-e7440-ultrabook/drivers.
Does the noise persist only when using any particular application? Have you tried checking using an external earphone with Mic?
Try the steps and let us know if you need any further assistance.

I've had the same on a Latitude 7400 for many weeks and Dell cannot fix it.
I've had replacement 2 x motherboard, camera, OS reinstall, obviously all drivers updated, devices removed and added from device manager, etc. and still it happens. This is painful.
