Front Panel Audio connector
If there are jumpers on any of the pins on that header, remove them, store them where you can find them, e.g. in a tiny bag attached to a screw inside the case.
E.g. I suspect the mboard when new comes with a jumper on the Audio out R and Back out R pins, and on the Audio Out L and Back out L pins.
If there were jumpers on pins, the jack for the same purpose on the back of the case on the mboard may no longer work (Mic and Line out, usually).
You don't need to connect to the pins for +5v and Mic power unless you're using a more expensive mic that requires additional power, and the case has the wiring for that.
MIC IN green - to the Mic pin on the header
(if that doesn't work, MIC BASIC yellow to the Mic pin on the header; one or the other. )
The mic jack wiring on the case is usually, and the wiring for it on the mboard for it in this case is, mono (one channel).
That's often the case with onboard audio, but on a sound card in a mboard slot, the mic jack wiring on the card is usually stereo (two channels).
GND black - to the GND pin on the header - when you have more than one GND wire from the case, they're usually connected together - it usually doesn't matter which GND wire you connect to the mboard header if it has only one GND pin.
(same applies to the GND wire in this:
SPKOUT L (it look like the SPKOUT R with two plugs ) red and GND black).
MIC BASIC yellow - see above.
"SPKOUT R ( in the plug there is a wire that leads to another plug same name)"
"SPKOUT L (it look like the SPKOUT R with two plugs ) red and GND black"
That's as clear as mud.
Is it marked GND, or are you assuming it's GND because it's black ?
NOTE that there is case speaker wiring from most desktop cases. It's either a 4 in a row one piece female connector that has wires only on the two ends, or it's two single wire female connectors, one wire of them is GND.
That would NOT have R or L on it / them.
Those wires connect to the Chassis Speaker Connector on the mboard.
They're probably NOT the same name, unless they're single wire connectors and one wire is Gnd, which is usually black.
If they DO have the same name, and one wire is for GND which is not usually done, you probably don't need to connect more than one GND wire to the mboard header, and
- the other wire for SPKOUT R goes to the Audio out R pin on the header
- the other wire for SPKROUT L goes to the audio out L pin on the header.
In that case, the ports on the back of the case for Mic and Line out will no longer work.
If one is SPKROUT R, the other SPKRIN R
and one is SPKROUT L, the other SPKRIN L
then SPKRIN R to the Audio out R pin on the header
SPKROUT R to the Back out R pin
SPKRIN L to the Audio out L pin
SPKROUT L to the Back out L pin
In that case, the Mic and Line out ports on the back of the case on the mboard will still work.
Internal Audio Connectors - those are for inputing sound only, R an L, a ground for each usually. E.g. from a optical (CD or DVD) drive.
You don't need to connect an audio cable from a modern optical drive to one of those, unless you want to be able to fiddle with the onboard sound's mixer settings do something you can't do otherwise . All sound from modern optical drivers is sent through the data cable to the computer.
