Hello, I have just upgraded my iBooks hard drive to an 80gb 7200rpm and the optical drive to a Superdrive. Everything has gone well apart from I have lost sound to the built in speakers. External speakers are fine. 99% of the time my iBook is docked so not a problem. However! the problem seems to be I cant get the audio speaker cable to connect to the little white socket. It does not seem to want to go in. Any ideas? Any help would be great as I love my iBook and hope to keep it going for a couple of years at least.
