On some older motherboard there was a 14 pins connector close to the audio system
called “JF-Audio1” with 2-3 jumpers, which you have to remove before connection, the
front panel sockets not to sure if still installed on present day boards?
Look in the motherboard manual for a Jumpers pin out setting called
“Front Panel Audio Headers” this will tell you how to connect the Mic, Front, Centre,
Rear Speakers connection
If not listed in motherboard manual your motherboard does not have the option to use the
front panel socket to connect a 5.1 Audio System
