Doesn't work for what? Headphone? Microphone? Speaker?

(Please different question on different thread...)

Use a commercial Windows Operating System transfer program to do that.
Quite a few steps involved and it is not trivial.
It is not just a "copy from this to that" operation.

You'll need to get a 4-pin OMTP to mic + headphone splitter cable, e.g.,
https://www.amazon.com/CableCreation-He ... B01KTBDE3Y

OMTP (in TRRS arrangement) is in left-right-mic-ground configuration.

Do not confuse OMTP format with the AHJ format which is left-right-ground-mic.

There are some detection circuit and (possibly) phantom power in MIC as well.
Call it a dark magic (or check Audio CODEC IC datasheet if you will.)

Basically, you'll need to only get three Left-Right-Ground leads out with a trivial cable, but you do have to satisfy certain conditions.
Blame modern technologies.

couldit possibly be because my headphones are a mic/headphoen combo but they only have the 1 pin not dual 1 for each
