built-in microphone is not working...no input device found

Question

I saw this question already posted, but it was closed. I followed all the steps, but it still couldn't find the built-in microphone. It worked while it was still under warranty

Answer 1

Dell support just found a critical driver for System BIOS. Installed the new driver but it had no impact on my microphone problem. If it can't find my internal microphone, is it possible that it somehow got deleted. If so, is there a way to reinstall the internal microphone

Answer 2

Internal microphones are usually wired directly to the sound card's audio input channel. They rely on the same audio driver.

Try to check if the mic is disabled in the BIOS. Follow the steps below.

Restart your computer.

As soon as the Dell logo appears, repeatedly tap F2 to enter the BIOS/UEFI setup.

In the BIOS, use your keyboard or mouse to navigate to:

System Configuration or Integrated Devices

This is where options like Camera, Microphone, and Audio Controller might appear.

Look for any of the following:

Microphone

Microphone Array

Internal Audio Input

Audio Controller (make sure this is enabled)

If the microphone or audio input is disabled, enable it.

Press F10 to Save and Exit the BIOS.

If you are not comfortable navigating through the BIOS, you may contact Dell Technical Support to help you over the phone.

Answer 3

Thanks for your help. I dove a little deeper into the dialog box that showed Microphone Array disabled and found where I could enable it. It's now working fine!!

Answer 4

That is very good to know. I am glad this has been resolved. Have a good one!
