Headset Problem

Hi. First off im only a teenager so im not very fluent in computer language so if you make a response, please make it as simple as you can.
Okay, so ive been having a problem with my headset where it doesn't show up on the list of devices. Its a headset/microphone and the microphone works so i thought the headset would work aswell. When i go to the list of audio devices (speakers, headsets, ect) the speakers show up (which i dont want to use) but my headset doesnt show up as a device, it only shows the speaker. I'm not sure how to add a device either and i dont want to disabe the speakers to see what happens. I asked my dad but he said that the device should automatically be picked up. If anyone knew what the problem was or knew how to fix it, i would be very appreciative.
