Optical out won't turn off. Internal speakers won't work. How to fix?
in my MacBook, the optical out is always on, as long as I don't have anything in the line out. Headphones just work well, but if I unplug the headphones or external speakers, my optical out will turn on and so the internal speakers of my Mac Book will still be turned off.
Is there any way to fix this, without replacing the whole logic board? I already tried to reach the little contact in the line out that keeps the optical out on, but without success.
Also I don't need the optical out at all, so it would be perfectly ok to just tell my Mac Book to stop using the optical out at all, if there is no hardware solution for the problem.
