Your jack or audio board is damaged. This is not a DIY repairable project. As a work around purchase a USB voice quality headset and microphone. USB audio is separate from analog.

Check your Sound control panel settings also check your WiFi & Bluetooth settings to see if you have an external speaker set. If these are all correctly set then your only left with the headphone socket as being broken.

You can try using a toothpick to move the switch contacts inside using a magnifying glass to see what your doing.

Then you have a bad socket switch or if you replaced the socket (desoldered it) then you have sorted something on the logic board.
