First time Cubase User - need help routing audio thru Cubase


I need to route a stereo in from my synth through the Built-in audio interface of my MB Pro (running OSX Lion), and hear the audio out the speakers/headphones/stereo out.

I see multiple “Built in Audio” options under Devices->Device Setup->VST Audio System. Selecting the 2nd option brings up the meters on the input channels on the main transport window. However, I’m unable to see any meters moving on the output nor am I able to hear anything.

Help appreciated on this!
