Hey everyone. So recently I bought a new CPU cooler that required me to take my entire motherboard out from my pc chase to install. So I do that and connect everything back. But I have 1 problem, which is that my USB and audio pins are dead confusing, the names on the pins dont seem to correspond with the names on given on the manual of my motherboard.
The USB front panel extension consists of 2x USB slots and 1x Audio and 1x Mic input. Even the audio and mic inputs are confusing.

Front Panel Audio:

The layout of my motherboards pins can be seen here .

Those which are connected to the front panel of the audio slots however are:

Green Wire - Spkout R

White Wire - Spkout L

Grey Wire - Spkout L

Blue Wire - Return L

Black Wire - Ground

Peach Wire - Mic In

Yellow Wire - Mic BIAS



The layout of my motherboards USB front panel connections looks like this


Those which are connected to the front panel of the USB slots however are:

Red Wire - +VCC

Yellow Wire - -D

Green Wire - +D

Black Wire - Ground

There are 2 sets of cables, one of USB front panel slot on and the other for USB front panel slot 2.

1. Peach- mic in
2. Black-ground
3.Yellow Mic Bias
4 NC
5. Green-spkr out R
6. nc
7. nc
8. X
9. Grey spkr out L
10. nc - "NO Connection"
Can't think of a use for the other 2 wires. Usually the case panel connectors have 1 or both of the connectors you listed instead of the individual wires you mentioned. Must be an old case.

As for the USB -
Red Wire - +VCC - 2

Yellow Wire - -D - 4

Green Wire - +D - 6

Black Wire - Ground - 8
And put the second set in the same order but in slots 1, 3, 5, 7

I've tried this twice it never worked. I tried connecting a headphone with a mic attached to it to the 2 front panel audio inputs, they weren't even picked up.
