I am building a retro pc and have paired it up with a nice crappy foxconn-th01 which is the cheapest and nastiest case i could find for the components I have. The motherboard is a Gigabyte-VM400M-RZ.
Now I would like to start this by saying that I’ve built upwards of 20 PCs for myself, friends and family but I’m sort of stuck…
I am having trouble with the front panel audio headers. I’m really unsure to hook this up because the pins on the motherboard do not match the description of what is on the end of the wires coming from the front audio header.
On the case I have the following :
On the first cable
MIC GRD
MIC POWER
MIC IN
On the second cable
HP OUT L
HP OUT -L
GROUND
HPOUT R
HPOUT -R
The motherboards description of the front audio panel is below:
This should be what you need to plug the HD audio pins onto the AC97 header:
On the first cable
MIC GRD = Pin 2
MIC POWER = Pin 3
MIC IN = Pin 1
On the second cable
HP OUT L = Pin 9
HP OUT -L
GROUND = Pin 2
HPOUT R = Pin 5
HPOUT -R =
The -R and -L pins should not be necessary AFAIK.
Getting those two pins onto Pin 2 for the ground may require a bit of a jumper wire. You can also inspect the board and see if there is any other ground pin on the audio header thats directly connected to Pin 2.
Thank you so much @catsay . I’ll give it a go. This is really helpful. There is a ground on the spdif header I can probably use, I was thinking the same thing. I’ll let you know how it goes.
