Hi, I just recapped a Mac Portable M5120 logic board. It has no sound to the internal speaker, the external jack works however. I found C9 (+) was not connect to pin 11 of the Sound Left Chip. C10 (+) was connected OK to Sound Right. I also found that the speaker (+) does connect to 2 leads on the external jack (see attached). Speaker is tested OK in my backlit portable. Any thoughts?
