Front Panel Audio Shunt Connection
| Many people have trouble getting the sound to work on a motherboard, that
they have no history about. One day I was having a problem with a computer I had
built, however it worked perfectly in the previous case it was in. Then I
thought to myself, what did the other computer have that this one hasn't? It
didn't have front panel audio!!!! So I grabbed the component out of the other
case, which was an ugly audio /usb thing that went into a floppy drive space. I
didn't want to install it in the front of my new case so I plugged in the audio
and placed it inside the case where no-one could see it. This solved my audio
problem immediately. All those hours I had spent trying to work it out.
Later I found out that you can put those little plastic jumpers onto certain
pins to enable your sound to work in a particular area. You need to research
your motherboard to find out what combination is right for it. Here is an
example below from the Intel® site.
The front panel audio header (J8B4) on the Intel® Desktop Boards listed
below has a jumper connecting pins 5 and 6 and another connecting pins 9 and
10. This connection is used to route the audio to either the front or the
back panel.

Caution: Do not place the jumpers on this block in any
configuration other than the one described below. Other configurations are
not supported and may damage the desktop board.

Note: To route the audio to the front panel, remove the
shunts as shown on the right and place the connecting cable from your front
panel audio solution on the header.
Caution: If you remove
the shunts and
do not place the cable from your front panel audio solution on the header,
you will not have any audio or microphone signals present on either the
front or the back panel audio connections.
