820-2850 no audio no trackpad

[Cocobill]

Hello,

I got this logic board 820-2850, replaced C9560 just to be sure, it passed EFI and OS ASD tests successfully. I installed a fresh High Sierra on an SSD and it takes 65 seconds to boot. When running, it does not appear slow, however I get no sound. Icon in the top bar is greyed out. In preferences the output is "Digital out" only, although I get a healthy chime on startup. Also, trackpad works fine but in preferences where I want to enable tap mode it says "searching for trackpad" What???

Any ideas?

Audio jack is bad, just remove R6805 and it will work again, just no more SPDIF. No idea about the trackpad thing, it works so you can only make it worse....
