Rispondi a "Optical out won't turn off. Internal speakers won't work. How to fix?"Be warned… This will come back and eventually the switch breaks. Yep, your speakers become unusable - ALL because of a minute switch that COULD have been given the option to be overridden from software. Rather than the fail-state being to lose the optical, it loses you your actual speakers. Apple used another seriously stupid solution here, specially considering pretty much nobody in the world uses an optical out anyhow.
