I changed the Flat and IO POWER several times, but it didn't work, can you tell me what it could be ?

The R1981 region had oxidation, I replaced the components, but no result.
AUD_IP_PERIPHERAL_DET 21mV without the headphone
AUD_IP_PERIPHERAL_DET 3.3V with the headphone connected.

Opem System Preferences and go to Sound tab.
Connect/disconnect headphones and tell us if both speakers and headphones appear there.
