No input devices found

I have a Dell Inspiron laptop that is unable to find the internal microphone. There is no input devices present in device manager even with "display disabled devices" and "display disconnected devices" on, and internal microphone is enabled in Bios settings. I have updated drivers and have the latest windows update.

Microphone was working perfectly a few days ago!! Any further ideas of troubleshooting?? I have tried all the common fixes
