The cause to your problem could be related to driver's installation or a wrong configuration in the application. The first thing you have to do is to check if the audio driver is properly installed on your computer. Go to Start > Run > devmgmt.msc and make sure that the audio drivers are installed properly. Secondly, use the application you selected for recording and check its configuration options. Choose the correct recording device and, make sure you are at least one microphone connected to PC through the pink input next to the headphones.
