Use - "Legacy AC'97 Audio Pin Definition"
AAFP
NC X X Line_out_L <-------> HEADPHONE_L
X NC
NC X X Line_out_R <-------> HEADPHONE_R
NC X X MIC2_R <-----------> MICPWR
GND <-------> AGND X X MIC2_L <-----------> MIC
Set the BIOS to:
"Front Panel Support Type" [AC97]
You use AC97 as the setting type, as your computer case wiring has
no SENSE_SEND and SENSE_RETURN.
Also, pick up the latest RealTek driver, from ReakTek. This
might not be the exactly correct page, and you may want to
start on the main web page, and find the correct download
file. The file listed on this page today is WDM_R149.zip .

As far as I know, all computer case wiring is some variation
on AC'97 compatible wiring. Connecting the five connections
above should be enough to make it operate. In AC'97 mode,
the system is not expecting to use the Sense function. The
built-in impedance sensing function inside the Hdaudio chip,
should detect the headphone when it is plugged in. Is
the headphone a normal 32 ohm device ? With some of the
HDaudio software, a dialog box should appear when the
headphones are plugged in.
There are some pictures of the Realtek software interface
here:

And if it still doesn't work, changing the BIOS setting
is all that is left to try.
