How to eliminate internal microphone noise in Linux
This article was published more than three years ago. Please note that it may be outdated due to new versions and updates. Try to understand the steps to follow in case you have to apply changes during the process.

In this tutorial we will reduce the internal microphone noise, which is due to the default amplification that many systems apply to audio input. The first thing we have to do is open a terminal (Ctrl + Alt + T) and enter the following command:

alsamixer

A sound equalization tool will open, we will press the Tab key to show different configuration panels, tabulate until the Capture view is shown (you can see it in the third line, as shown in the image), we move through the bars with the left and right arrows and adjust them with the up and down arrows.

The options should stay as:

Mic Boost: 0<>0
Capture: 100<>100
Internal Mic Boost: 0<>0 or 22<>22
