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.
