As I understand it, you want the audio from a video clip to be present when you transition to a camera?

There is two ways (as I know) you can acheive this, the easiest one is as follows:

1) Make sure you have the camera as an input, and the video clip as an input
2) Create a new blank input (Choose 'Transparant' under the 'Colour' category in the 'New input' window)
3) When the new input is created, doubleclick at the input (or click the cog-icon) to open settings for the input
4) Under the 'Multi View' tab, choose your video clip input as Layer 1, and the camera as Layer 2
5) Make sure that the video clip is not visible, otherwise, drag it out of the canvas
6) Also make sure that it has the setting "Automatically restarts with Transition" is ticked

You can now use the new input (the transparant input with two layers in the multi view) as you camera.

Hope it makes sense.
