Removing AUDIO IC
It's an issue caused by a bad connection on the audio IC chip, the chip will need to be replaced which can only be done. Reballing the chip can fix the issue but replacing the chip, reinforcing weak solder pads and use of jumper wires for broken pads on the logic board is a better option. People who repair Apple products say that a grayed-out speaker icon, issue one of the pads that connects the audio chip.
