Macbook pro 2017

[sebastien_czech]

Hi all,

I have a Macbook pro 2017 with logic board 820-00840 that has no audio.

No audio hardware detected.

I don't get HDA_RST_L which should be 1.5 volts.

This voltage came straight from CPU

Any ideas how this voltage is produced? Apparently depends on PCH but they seems to be working fine.

Regards,
Sebastien
