Hello guys, I'm trying to repair my headset and I found out that the pcb of the 2.5 jack connector is pretty much garbage. Luckily I can bypass that since it's just a pass-trough, but I can't find anything about the jack connector's pinout.
Could you guys help me with identifying the pcb?
Maybe I'll find something that way.

I'd use a multimeter to look for continuity from one spot to another on that PCB. It's pretty banged up but I think you could get at least two of the contacts sorted out with a meter. That would dramatically reduce the permutations to test.
