No speakers (but headphones ok) after logic board removal battery job
I followed the full instructions from iFixit to remove most of the guts of my laptop in order to do a battery replacement, as described here:
Reemplazo de la batería de MacBook Pro 15" con Pantalla de Retina de Mediados de 2015
Upon completion of the job, everything works except there is no sound whatsoever from the speakers.
I get sound from the headphones just fine if I plug them in.
If I unplug the headphones, the system preferences correctly sees that it should be feeding sound to the internal speakers (so it is not just stuck thinking it has headphones). Yet I get no sound whatsoever from either speaker.
What should I check?
Es esta una buena pregunta?
