  • You need to identify your hardware, how you are connecting the microphone, and what application you are using. Often Desktops are on configured for audio recording, use Ubuntu studio.

    I am using Ubuntu Studio. I dont know what you mean about indentifying my hardware... I am looking for an answer on how to turn off the automatic changing of my mic volume. It is something like detecting that my voice is too low, so it raises it up, but I want to disable that. I use skype and I dont need to be loud.

This is not meant to be a reply but a comment. I have a similar experience with my laptop when Skype is turned on. In your screen shots it looks like you use Skype as well. Maybe you can see if the problem disappears if you turn it off?

Edit 1. In Skype's Options --> Sound uncheck the tick that allows Skype to automatically control the volume settings.

Edit 2. If it is not Skype, I am afraid I do not know how to resolve this issue. In any case, is this question not a duplicate of

How to disable microphone from auto adjusting its input volume

which after two years does not seem to be fully resolved.

    If problem is while using zoom: Setting -> Audio -> Uncheck "Automatically adjust microphone volume". My issue is resolved this way.

    Thanks @NasimuddinAnsari ! Seems like you've just solved my problem! Seems like zoom is forcefully changing system's input volume. I will come back, if problem does not resolve by this advice.

I think I have an answer for this, it worked on my machine and it's only a theory. I have three mics on my machine, one built into the desktop, one on the camera and another on my headset. I found that if one of the other mics picked up sound, it dropped the gain on the others. I disabled the camera mic and unplugged the desktop and the headset is working fine now.

Not sure if this helps anyone, but thought it worth mentioning.
