Without more information about your case or motherboard, this information may be of some basic assistance: Installing Front Panel Audio Plugs. I strongly recommend you refer to your motherboard manual before attempting to change any connections on your motherboard.

The Realtek are the best and easiest way to configure your audio jacks. The Realtek drivers do make it possible to set the audio output to the mic in/line in jack on the front and rear panel.

Open the Realtek HD Audio Manager. In the top left corner choose the underlined option Device Advanced Settings. If you are dead set against using Realtek drivers look at this link. How to remap / retasking Realtek onboard jacks / ports
