Customer brought me a MacBook Pro A1286 (2011 model I think) that doesn't produce any sound, except for the startup chime. No devices show up in sound preferences, even after doing an upgrade install.
Got a tip for us?

Startup chime but no sound devices

Did you plug in headphones to see if sound was present there? That particular model has a bad habit of a sticking switch in the headphone jack. The machine then thinks that headphones are plugged in and therefore no sound to the speakers.
Chime works because that's pre-boot.
You can try to fix the headphone jack by plugging a pair of headphones in and out several times to see if you can unstick the switch. Sometimes that works.
