    • Start with your laptop off with the case & hinge open

    • Turn on the laptop. After this point be very careful not to touch the board especially with anything conductive.

    • Once your Mac has booted, carefully navigate the OS to play a long audio track that will keep playing for the remainder of this guide.

    • If you experience the issue this guide is intended for, no sound will play but a red light will turn on in the headphone port.

    • This silent audio will be used to find the source of the problem later on.

    • The headphone jack is shown with a red ring.

    • Wear a grounding band or at least ground yourself before proceeding.

    • Apply gentle pressure to the 2 areas marked in blue with your finger.

    • This pressure slightly flexes the area and may cause poorly soldered pins to re contact.

    • If the sound returns and the red light turns off the issue is likely caused by a poor solder connection on the board. If not this fix may not work for you.

    • Using a piece of wire or a pin or a small paper clip, you can test each pin. You are trying to touch each pin to its surrounding solder connection.

    • Be careful not to bridge any pins to each other.

    • Pause on each pin and see if the sound starts playing when you probe each one.

    • You may need to probe more than one pin at the same time. Look for pins that have a visibly poor solder joint.

    • Identify one or more badly soldered pins.

    • Turn off your machine before proceeding.

  4. MacBook Pro Audio Stuck on Digital Out, Re-solder the poor contact(s): 步骤 4 中的图像 1,1
    • Reflow and add some fresh solder to the bad pin with a fine tipped soldering iron.

    • Do not over heat the area but make sure the original solder has started to reflow.

    • Here you can see my bad pin with a new fillet of solder.

    • Screw the case back on your mac!

结论

With any luck you should now have reliable sound via your speakers and headphone jack.
