I can hear you now

Mein Problem

At first all audio devices intermittently disappeared. Resetting PRAM etc. stopped working. Eventually the only way I can get audio was with a USB mic and speaker.

Meine Reparatur

The repair went smoothly following the step-by-step guide. After reassembly and restarting the computer audio was back.

Mein Rat

Use a magnetic sheet to organize the many screws as you remove them--a flat "refrigerator magnet" will do.

Don't tack down the adhesive near the audio board until the board is connected and screwed down.
