It doesn't cost much to replace the audio jack. But you need some good soldering station and hot air station (not China cheapo). First, open up the device and see (use microscope not magnifier) if the solder joint at the base of the audio jack are still intact. If intact without breaking out, replace the jack as it might yank the contact inside the jack. If the solder joint is cracked without damaging the pads, just use some flux and solder to get it back. Now it is your call to open up and check inside. Better not to rush and it need patience when working on the small components. Do not worry about static or ESD or what ever. I have been working on the Mac at component level and I don't even use ground wire on my desk.
