a7v600-x audio front panel isue

[crazyfrog]

Hi.
I am trying to make a front panel for some old mb - ASUS A7V600-X cause the case where I am having it is quite old too and the audio front panel is missing. By default the mainboard has 4 of the pins connected by 2 jumpers like the image shows.
This is the scheme from the mainboard user guide.
Now, I am having a stereo out jack and a bunch of cables with pin connectors at the end and I'm thinking to make myself some audio front panel.
In the user guide is saying that for using the audio front panel I have to take out those jumpers.
Do you have any idea how should I connect those cables (l,r and gnd) from the stereo out jack so I will have a working audio out that will cut off the back sound when I connect something in front? I don't care about the microphone, just want to make the audio front to work.
Thx.

just connect the cables instead of the jumpers

I already connected the r, l and gnd from the stereo audio jack to line out_r, line out_l and agnd from the mb but I am not having any audio back signal anymore.

id say you have to put the leads on just as the jumpers are placed, i.e. line out_r to r positive and BLINE_OUT_R to r negative and the same for l.

But my stereo out jack has only 3 wires. left, right and ground... where to put those 4 wires?

bline_out is the common ground for the line out.
