Cubase not recording from line in on a macbookpro

I have a brand new Macbook pro and just installed Cubase Elements 6. Any idea how I get cubase to recognise the line in, all it does is pick up the internal microphone ? Garageband picks up guitar from the line in ??


Quit Cubase.
System Preferences / Sound / Input Tab - select Line In.
Launch Cubase and if necessary go to your VST device and select the built in audio.


Thanks Hugh, I tried that but Cubase is still only picking up the internal mic not the line in ??
