You mention NC and NO jacks. NC, NO = normally closed and normally open.
Since these are opposite in their effect and your complaint is they are opposite as to Windows, maybe you need the NO jacks in this system.
Hi! So, I just bought myself 6 Normally-Closed 3.5mm jacks and they seem to have a bit of an issue on my PC: they reverse the connected/disconnected functionality (when I physically connect headphones, they show up in Windows as disconnected and when I physically disconnect them, they show up as connected).
Now, all my cases have 3.5mm jacks that correctly work with my PC, so they are alright.
What can be the cause of this issue? All my cases (3 cases) have Normally-Open jacks or could I have soldered the jack wrong?
