Windows 10: Windows 8.1 doesn't recognize my internal microphone. What can I do?

Windows 8.1 doesn't recognize my internal microphone. What can I do? I have a Inspiron 15 Series 7547 i7 processor with Windows 8.1.

Microphone doesn`t work

My microphone and ear-phone doesn`t work. Please help me, I have windows 7 home basic, my computer reproduces a sound, but devices no.

 

Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?

 

Internal Microphone; Gone After Windows 10 Upgrade

My internal laptop microphone worked until I upgraded from Windows 7 to Windows 10. I first noticed upon entering a Zoom meeting and no recording devices were recognized. This was one day after successfully using the microphone with Windows 7. Here are observations
from what I've tried:

• I have allowed mic access in privacy settings
  
• There's no input device found in the sound settings
• I can't "test" the microphone because it's not recognizing one
• When I "troubleshoot," the device list shows two microphones; however, it refers to audio jacks, not an internal microphone
• I went to the Device Manager to see if I could update the microphone drivers; however, no drivers are listed here to update

I'm at a loss for next steps. How do I get Windows 10 to recognize the microphone in my laptop following the Windows 10 upgrade?
