How to fix Chrome's Mic volume auto adjusting?

So this problem has been bugging me for a few months now. I purchased my laptop last year. Everything was fine but some time in Feb 2021, Chrome started auto adjusting microphone volume. Specifically speaking, I (have to) use Google Meet and MS Teams. The problem happens on both websites.

The problem does not happen when I am not in a meeting. When I am in a meeting, Chrome auto adjusts mic volume, and increases it when I am not speaking anything. So when I actually speak, my voice sounds too loud to others.

I started attending meets on my old PC because for some reason, my PC does not suffer from this issue. But tomorrow I’m supposed to attend a meet as an instructor and the demonstration requires me to use my laptop. (PC is too low spec)
So I really need some fix.

Someone else also reported same issue here :point_down: The report is about Hangout, but I have exact problem with Meet. Unfortunately, their discussion does not reach any conclusion. :cry:

In case it helps, the problem does not exist on Discord.

Hardware - My laptop has a single 3.5mm port for both input and output audio. I plug in a generic mobile earphone in them. Issue also exists if I use laptop in built mic. The increase in volume that I talked about was monitered using pavucontrol.

I am using pulseaudio not pipewire. Also, output volume does not change.

There seems to be a plugin that claims to fix. I’ll install it, but don’t know if this will work or not.

If anyone else faced this issue, or know a fix. please share :pray:

PS. Another issue is that I don’t have any way of verifying if a certain proposed solution works or not. The volume adjustment happens randomly.


The plugin fixes the issue with Google Meet on Chrome. On MS Teams desktop application, you can disable auto mic adjustment in settings.

If joining Teams meeting as Guest from web browser, I don’t know any way to fix the issue.
