Check the output of your bussed VI audio track. It should be set set to Analog 1-2.

Your chain of events should be:
Open a new stereo audio track
Set the input to Bus 1-2 or 3-4, 5-6 etc depending on what is available
Set the output to Analog 1-2
Set the output of your VI track to match the input of this new Audio track
Click record enable on your new Audio track
Click the play button and let your VI audio record to your new Audio track
Take your new Audio track out of record enable and click play
You should now be monitoring your new Audio track

Of course there are many different and more complex ways to route signal paths. Hope this helps...
