So, I have a problem. About once every three times I reboot my Pro, the speakers don't work. The sound status slider in the menu bar is greyed out. Trying to increase the volume simply shows the Volume pop-up also greyed out. I can fix it, but only by plugging in headphones and then removing them. That's fairly simple except I don't always have headphones on me. I haven't been able to research it super thoroughly, although some threads on Apple's support forum seem to suggest that this is in fact a logic board issue. Is that right? I do have the warranty still, and I'd love to get this taken care of before it runs out. This has started happening after one of the following: Installing a Kingston SSDNow V+ SSD, installing more RAM, or installing 10.7.1 combo update. I can't say which it started after, since I did all of those very close to each other. I have reinstalled Lion when I upgraded to the SSD, as well as resetting the pram. Any thoughts/suggestions?
