Need help with connecting an old case's front panel audio to an H310-F PRO motherboard.

[aaronisnotded]

As indicated in the Title i need some help T-T

 

The old case's connectors are indicated as following:

MIC IN

MIC BIAS GROUND

SPKOUT R

RETURN R

SPKOUT L

RETURN L

 

and THESE are my motherboard's pinouts. I literally have no idea how to arrange them as they're very different, anyone know how to help? thanks a lot in advance.

What age is the motherboard as the case might be AC97 and the board might use HD audio connectors

Yes should be easily doable.
As i've seen cases coming with connectors for both.
I hope this picture helps.

Just seen the motherboard model in the title. It will be HD audio but the case connectors your describing look like AC97

Thank you for explaining the question in the first post.

I remember this being a common problem when we first introduced HD audio on motherboards.

Very much agree.
Until cases finally came with this:

im not sure, the motherboard is relatively new though, but the case is probably VERY old

Update: it didn't work. tried exactly the same thing that was shown in the table above, its emitting some static noise but thats about it  not sure what else i could try, suggestions?

You can't go straight from one to the other with make some alteration. If you look closely at the picture posted above you can see a two pins which are jumped across. You can by adaptors to go AC97 to HD but you can't go the other way without adding some resistors. As HD uses a resistor tree.

im not entirely sure i need this because it works apparently!! i went to realtek console and checked "disable front jack detection" and it works!!!!!!! except theres this really annoying static that i cant get rid of.. no idea how i will but at least it works i guess!

[abit-sean]

Jack detection works using the resistor tree I spoke of before, so disabling that makes sense. Static might caused by a bad ground, check the grounding cable is correctly seated

[aaronisnotded]

oh my god THANK YOU for some reason i unplugged the ground and it works literally just fine now, thank you so much!!!!!!

 

EDIT: SCRATCH THAT I FOUND THE ACTUAL PROBLEM IM SO STUPID

 

MY FRONT PANEL HAD USB PORTS AND I HAD THE WIFI DONGLE PLUGGED ON THERE, AS SOON AS I REMOVED IT, EVERYTHING WORKED JUST FINE, THANK YOU EVERYONE!!!
