Greetings, I have this board that has no output from the speakers, however it detects the output device, as well as plays from headphone jack, and recognizes mic input.
It is switching back and forth without issues to speakers/headphones when unplugging the jack.
Tried replacement speakers - no dice.
No visible knocked out components nor liquid damage.

What would be your starting point?

Volume control bar is active, when pressing the keys?
PPBUS_G3H_SPKRL present?

Do PRAM and SMC reset 2-3 times.
