    Hello guys.

    I am working on a Macbook Air 2015 logic board 820-00165 that has no sound. There are no audio device visible.

    Replaced audio DC Board.

    Reflash bios (clear ME)

    Replaced SMC

    For some reason it still don't give any sound :)

    So I am now tired and it seems this board will soon go to the bin.

    There are no corrosion on the board and I also replaced U6410 :)

    Maybe somebody on this forum could guide me.

    I don't understand how the sound is produced exactly on this board.

    J9500 looks fine all pin are connected and no corrosion.

    thanks in advanced for response.
