MacBook Pro M2 - Mic input's level is not working (the mic is, but too low)

I have the same problem. After using the mic in Safari. It works again after restart Mac or quit Safari.

"MacBook Pro M2 - Mic input's level is not working (the mic is, but too low): I have noticed, that after using Google Meet in Safari, the browser keeps using the mic. No matter if the window (tab) is already closed. This prevents setting the volume up and down for any other application, and one needs to quit Safari and open it once again to make the mic work again.”

So, did you try anything I mentioned in my previous reply?

If nothing worked, you’ll have to perform the following:

Reinstall the macOS:

Go Here: How to Reinstall macOS from macOS Recovery - Apple Support. Important: Be certain to create a backup of your Mac prior to all of this. That way, you can have something to restore from the Mac from, should anything go wrong with the reinstall. Once reinstalled, try this once more.

"MacBook Pro M2 - Mic input's level is not working (the mic is, but too low): As you can see in the video, I cannot set the mic's level; it is always too low. To make it work again, I need to restart my Mac, which is annoying if one has different meetings throughout the day. Video: https://youtube.com/shorts/6lLIiWVZFpw Thanks!"

You are welcome.

Troubleshoot the Mac Microphone:

What to Try:

• Unmute the App:

If an app has its own audio input settings, then perform the on the app itself.

• Remove External Devices:

Verify what your output item is.

• Disable Bluetooth:

If there are any microphones nearby, then they may be getting in the way via bluetooth.

• Go Here: Control Access to your Microphone on Mac.

See if an app is permitted to use your microphone.

• Reset the SMC and your NVRAM:

Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for Sound) become manipulated, technically. So, reset the SMC and NVRAM.  (Applies to Anted-Based Macs Only)

• Boot into Safe Mode:

When you boot into Safe Mode, items load by default, with certain settings and caches set aside. Go here: Start Up your Mac in Safe Mode - Apple Support

• Create a New Administrator:

See if creating and logging in as a new administrator does the trick. There may be something misconfigured in your current user - something that is getting in the way. Go to: System Preferences > Users & Groups > Unlock > Click: "+" > Create the new administrator

This is so true! This problem comes from Google Meet! After using it, my microphone stops working!

Seems like an issue with the audio service (most likely gain levels get borked). Restart the audio service by killing it, run:

sudo killall coreaudiod
