    • 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.

  2. MacBook Pro Audio Stuck on Digital Out, See if your issue might be caused by a poor contact: 手順 2、 2の画像 1 MacBook Pro Audio Stuck on Digital Out, See if your issue might be caused by a poor contact: 手順 2、 2の画像 2
    • 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): 手順 4、 1の画像 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!

終わりに

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