Right-click on "Computer" (or "My Computer", depending on your version of Windows), choose "Manage", then drill down on Device Manager and expand "Sound, video, and game controllers".

If all that your Device Manager shows is something like "Microsoft High Definition Audio Device", that indicates that you are using a default/generic driver, which may not be suitable for your hardware. If you are just using the integrated audio device on your motherboard, then just provide the brand and model number of your motherboard and we can look up what audio device it has onboard.
