That's why you have a switch for 'Automatically adjust microphone settings.' We found this automatic management to be reliable, especially for avoiding microphony. By default, Skype manages this level automatically. The next adjustment is the volume level for the microphone. Check whether you plugged it into the correct port. If there is no improvement, your microphone might not be correctly plugged into your Windows PC. You can repeat the process of changing the device until you select the correct microphone that works. If you have made the correct selection, the microphone input bar starts to color its dots while you talk, showing the input level. You can test your selection right away by speaking into the microphone.
