How to solve the problem of no sound from the microphone in win7

When using the win7 system, sometimes you may encounter that the computer's microphone has no sound when speaking, and it does not work no matter how you adjust it. At this time, you need to try to rule out whether it is a software problem or a hardware problem. Or just plug and unplug our headphones and microphone again.

What to do if win7 microphone has no sound:

1. Check whether there is a hardware problem
