Noise with microphone

Hi all. I’ve a problem with microphone on my laptop: I can ear a high noise when I try to register something. It can depends from drivers or the microphone could be damaged? How can I check it?
Thanks

Hi, no one can help me just about what I can start to check?
Thanks

What desktop environment are you running? Have you installed Pulse Audio Volume Control? Also, what do you have for audio devices? I notice that these newer systems have numerous audio outputs.

One can get noise in their PC microphone’s recording if one has the record volume/gain too strong. I like to initially test my microphone at levels around 65% or so, and once that is established as functioning, I turn up or down the record levels from that baseline, to better tune the recording.
