i was trying to sting the red light “sensor” (it’s a little pin of the audio jack) with a needle, it works for me like 3 months, but i have a friend who loves the wired headphones, aaaand my audio it’s down again. does someone knows how to kill the optical audio, without kill the audio jack? like cut a pin and let the audio jack and internal speakers working. please, help, i really love my mac

Hey there, have you tried this?

  1. Plug in headphones or external speakers into the line-out jack
  2. Shut down the computer
  3. Perform an SMC with the speakers still plugged into the jack
  4. Boot up
  5. Disconnect speakers

Blow into it very hard.
