Connecting headphones mutes the internal speakers. Or are you saying that you do not get any sound even when no headphones are connected?
If so, you could do worse than carefully cleaning the headphone socket with a toothpick.
Hi sorry -- wasn't clear. I have sound with headphones - no problem. I have NO sound with internal speakers since a couple of days ago. Have done the reset of PRAM and nothing changed. So there is clearly a problem with the internal speakers or the link -- but sound does come through headphones so it's not a generic 'sound' problem. Clear? Thanks!

Thanks --- no bing at all. Finally called Apple as it's a brand new machine. They have decided to replace it. Alas, I'll need to reload all the itunes etc --- but hope that will solve the problem. Thanks for the help!
