PC front panel 3.5mm jack socket replacement

[Erling]

I have Zalman Z3 case and Gigabyte HD3P motherboad (HD Audio supported). Front audio panel has 2 separate 3.5mm TRS jacks, one for headphones and another for a microphone. I'd been using front panel with zero problems for several years, but recently my Realtek HD started to report random disconnections: sometimes mic disconnects, sometimes so do headphones. Usually they "re-plug" automatically, but interruption bothers me anyway, so I decided to replace 3.5mm jack sockets in order to avoid random contact failure. Headphones and mic are definitely not the source of the problem since they work perfectly with other PCs.

I easily opened the case, took out the front panel PCB and desoldered both jack sockets. They look pretty normal, like this: https://i.ibb.co/2qFf4VL/3-5mm-Audio-Socket-Phone-Jack-3-5mm-Headphone-Jack-Types-Pj-3f07.jpg

What I didn't know is that they have 5 pins instead of 3. I've already read some manuals (like here, here and here), so now I understand how detection works. But I have one concern. Most circuit schematics for 3.5mm jacks with detection pins specify that detection pins and respective signal pins are normally shorted/closed (NC). But the sockets I'd desoldered are quite the opposite: looks like detection pins and respective signal pins are normally opened/disconnected. I lurked through the web more and found numerous mentions of a following statement: "NC 3.5mm jack sockets are used for AC97 standard, NO 3.5jack are used for HD Audio standard". This is quite confusing since I can barely find a vendor who would advertise 3.5mm sockets as NO. Almost all available sockets seem to be NC.

My questions are:
1. Is it true that HD Audio front panel requires 3.5mm jack sockets with normally opened detections pins?
2. If yes, can I rebuild/rewire/hack NC sockets (or HD Audio front panel) so that they will work with HD Audio properly?
