Sonata II has a seven wire audio cable. The cable is compatible with
AC'97. Connect only five of the wires. The RET-L and RET-R are
not connected, and can be left dangling. You do want to
connect MIC, MIC-BIAS, GND, FPOUT-R, FPOUT-L. The first two
are for the microphone on the front panel, while the last
two are for the headphone jack. The ground signal is common to
both jacks.

Now, get the PDF version of the manual for the motherboard.
In section 5.2.1, is a subsection "Configuring AC'97 Audio".
It mentions a Windows dialog with a tick box for "Disable
Front Panel Jack Detection". That disables the HDaudio
method of jack detection, and should cause the audio chip to
switch to impedance sensing. Impedance sensing is how AC'97
codecs would automatically detect the front panel headphone
and microphone. So when the "Disable Front Panel Jack Detection"
is ticked, your AC'97 front panel wiring should begin to work.
