My speakers and headphone jack do not work/no output device?
I recently did a rebuild due to water damage on a 2009 macbook A1342. I replaced the uppercase, keyboard,and trackpad. All of the other parts are original. Since then, however, I have been without sound. The volume controls when pressed are dimmed and when I go into system preferences their are no output devices found. When I rebuilt the machine I saw no burns or anything that would indicate that any damage has happened to the MOBO, but I'm no expert. I was hoping someone knows the answer to this puzzle. Even if I can't fix it I would love to at least get a diagnosis.
Is this a good question?
