I tried to connect a microphone to my computer that I found in my scrap material, but when I started the recording application, nothing happened
Both microphones and computer sound cards have different characteristics, especially in relation to older ones. Thus, it may happen that a microphone that works on one computer does not work on others. You should always test the microphone and if it does not work, do not discard it, as it may just not have the characteristics that make it compatible with the application and can be used in another.
