Welcome to!
Your motherboard manual should show a diagram of the header for audio connections, and their specific functions. There should be a page with a diagram that came with the case.. for how the audio connections are designed. If not, then go to the Web site of the case manufacturer and see if it is available.
If not, then it means a removal of the front panel to determine what leads are for what purpose.

Generally, the header on the motherboard requires two small jumpers to enable the rear audio ports, unless the front panel setup is used. By rights, the front panel leads should be separate, not in a single header block. And there should be small printed notations on them as to their function.
When using the front panel audio jacks, the rear ones will be disabled.
There are different types of microphones. The standard crystal type with high output, the magnetic type with low output, and the condenser type that requires a bias voltage to work.
Too bad a standard isn't adhered to with front-panel audio setups.

F@H.. to solve mankind's maladies.. in our lifetimes!
