The first thing to check is the correct microphone connection. On a laptop, such problems cannot be, because it has a built-in device. But on the computer, the external device must be connected to the appropriate connector. It is usually located at the back and has a pink or red color - although there may be other color options, and the panel for connecting audio devices to modern PCs is often performed from the front.
In a laptop, on which to improve the sound quality, you can also connect an additional microphone, similar connectors are located on the side.
I just constantly work at the computer, writing articles for one site, and faced various problems.
