MacBook Pro 16 Internal Mic Volume not Working

The input volume of the internal microphone of my MacBook Pro 16 has suddenly set itself to zero, and whenever I try to move the slider to a higher level in sound settings, it bounces back all the way to the left. Any USB microphones that I connect to the laptop work well without issues. My theory is that this could be related to having recently enabled dictation, which I understand triggers a driver/software installation that may have gone bad. I know that is not hardware related since dictation works well with the internal microphone when activated (volume set up independently) but not with other applications . I did some troubleshooting such as resetting the PRAM and SMC and creating a new user but none of them worked. I will appreciate any suggestions you may have.

MacBook Pro 16″, macOS 10.15

A. Try Safe Mode:

Boot into Safe Mode (Hold Down: shift key upon boot). See if this bouncing stops. Items like login items APFS our aside an corrupted temporary, unneeded files are deleted.


B. Update your Mac:

Perhaps there was fix for this in the most recent update. So, update your Mac: Go to: Apple menu > About this Mac... > Check for Updates...


Important:

Prior to Updating, Back up your Mac:

Create a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the update.


Also


C. Reinstall the Drivers:

As for software going bad, uninstall the software > restart your Mac > reinstall it.
