If this is what it looks like http://www.motherboards.org/imageview.html?i=/images/reviews/motherboards/1793_p3_14.jpg, the header was designed to plug a panel connector from a case.

All you need are the two audio pins (left and right) and the ground - pin1, pin3, and pin2.  There may be a sensing circuit to turn off the main speakers when the headphones are connected.  Apparently, you have provision for a second set of headphones in pin5 and pin9, along with ground.

Many modern motherboards have configurable jacks - see if the second headphone will function as a mic connection.  This thread may also help if that doesn't work: http://www.daniweb.com/forums/thread60797.html#

MIC jacks are powered.
Easter egging those connections can be a real bad idea.

MIC connections are +5vdc, Signal, and Ground.
The one Ground is for both Signal and MIC DC power.

Use a multimeter and find which pin is +5vdc.
There will be a ground pin next to it which you can ID by resistance checks to another ground.
[Resistance checks with power removed....]
The Signal pin will be next to them so once you know the power pins the Signal pin may be obvious by the layout.
If not then easter egg just the Signal pin avoiding connecting to +5v in the process.

Hey Fraher,

If your cable from your case is in ONE plug, just plug it in to the F audio connector directly. There is only way it could fit, so do not worry.
Now, if your cable from the case is the old fashioned way, where they are in independent wires, follow this photo:

That fconnector is simply your front panel connector, so if you wanted to connect a mic/earphones to front jacks of your case, you can do so. So even if it says earL, it's safe to put in audioL of motherboard connector.

Just follow the photo above, you'll be good.

On a side note, this will work if you are going to use integrated sound. If you ever purchased let's say, a sound blaster audigy card down the road, and you disabled the onboard sound, you'll lose the front connections. Some sound cards allow you to connect the front input cable directly to it.

Best wishes.
