Hi @khboldbaatar ,
If the audio socket is damaged internally it cannot be repaired, it has to be replaced.
I cannot see any markings on the socket itself which would help to identify it so that the configuration of the connections was known so finding an exact replacement will be difficult.
You may have to replace the whole IO board which has the socket on it.
