It might think that you have connected an optical cable (is the port glowing red?) or that you are sending the sound through HDMI instead. If it's the former, try connecting your speaker/headphone cable and wiggle it a little. If it's the latter, check the sound settings in System preferences.

i think it might be the latter, as ive got it connected up to an external display, running hdmi via thunderbolt. –  sam Mar 28 '13 at 17:27
