Hi I have a damaged headphone jack on a MacBook Pro. It causes the computer to think that digital output is on. I have played with the jack and can’t get the switch to go back to built-in speakers. Is there a way to bypass the headphone jack completely by soldering a wire? If so, what fuses do I need to solder? Thanks for your help. It’s really frustrating to hear a startup chime but not have any speakers in the OS. I have reinstalled, looked for a red light, etc. and think my only option is either a new logic board or to figure out how to bypass the jack.
Try a USB audio dongle - (you can attach headphones or external speakers to them - USB audio is separate from digital and analogue audio) don’t solder on your logic board or your have more problems. If this answer is acceptable please remember to return and mark it.
