Problem Sony Xperia E5 and E1 microphone repair


With E5 F3311, I have 2 motherboards, one does not start and one does not record video with sound, the rest works, can it be repaired? I guess the microphone changed on the board? do we do such small solderings?

with Sony xperia E1 D2005 it worked until I cleaned the microphone hole with the toothpick and .... and I can't hear the sound anymore, I can't hear what I'm saying in the conversation?
