Disable Automatic Gain Control

Although I hope this bug will be fixed quickly.

Have you tried the Safe Mode boot?

My work around is to force the MacBook to use the internal mic rather than the headphone mic. The OS seems to not try to regulate the input volume of the internal mic.

Good luck all...

Hello masoud_soroush,

After reviewing your post, it seems like you are using a wireless headset on the MacBook Pro and the mic mutes and will not unmute.

Does the headset disconnect from the Mac?

Are you using the mic on the headset or the internal mic on the Mac?

If you use the mic on the Mac does it work on calls?

Take a look at the Resetting the headphones to factory default settings section.

Please don't hesitate to let us know if you need additional assistance.

Thank you for using Apple Support Communities. Have a nice day.

I have spent about four hours with Apple Support on the phone, cumulatively. The developer contact eventually admitted that

• The headset muting spontaneously issue is a bug with Monterey.
• They may fix it someday.

I have a hack that seems to work. I play music in Spotify on my Mac at the same time as i'm on a call (in Google Meet) and then the headphones don't randomly mute. I'll post if this hack stops working.

I solve this "automatic" mute when i downgraded my OS from Monterey back to Big Sur. Presently, mine was permanently resolved

This worked GREAT for Google Meet! Use this plugin: https://chrome.google.com/webstore/detail/disable-automatic-gain-co/clpapnmmlmecieknddelobgikompchkk

Issue was fixed in MacOS 12.4 for my Airpods Pro.

Using Mutekey: https://apps.apple.com/nl/app/mutekey/id1509590766?l=en&mt=12 with a keyboard shortcut to mute the active mic.

Yes this is ridiculous and clearly a Monterey bug. I noticed that my AirPods work fine. It is only 3rd party bluetooth headphones with a Mic that are defeated by Monterey. Apple - issue a software update now!!! It's ridiculous in the pandemic state. I can no longer have private web meeting and have to shut off my headset and use the Mac mic and speakers. Fix it now please.

FYI my headset model is also the Aftershokz Aeropex.

thx

I will add my case to this list as well. Currently running 12.0.1 on MacBook 16 (Intel). This exact problem began right after upgrading to Monterey. All browser-based video/audio recording and meeting systems are affected including VOIP calls. At some random point, while I am talking, my Plantronics V8200 headset (using a Bluetooth connection) will go into mute mode on the device. I am able to unmute on the device. The audio/meeting/VOIP software does not mute during this bug. This bug only occurs when I am talking, it does not occur when I am quiet.

I have installed the Bluetooth Explorer, the recommended setting above did not fix my problem.

In the bluetooth Status I see, during a call (when the mic is on) the Connection switches from Audio ACL Connection to SCO Connection. These seams to be normal. But during these SCO connection the Mic will be switch to mute on and just after to mute off which results in a pause of 3 Sec while the Mic is off. What I need is a hint how to observe and fix these SCO connection. Yes before the update to Monterey all was working fine.

Apple doesn't monitor these forums. Tell Apple about your problems via Feedback - macOS - Apple so that they know others are having the same problem.

Actually it is still present on Google Meet, since it doesnt have the option to disable auto changing input mic volume
