Hey guys,
once an audio clip is added to the scene director you have to expand the track with the small black arrow button at the far left of the audio track on the scene director. Once expanded it will reveal a blue line representative of the audio level.
To adjust the level you must add at least one keyframe to the clip to perform the click and drag operation. To do this position the play cursor on the desired frame then click on the red circle button exposed in the audio track when you expanded it. This will add a keyframe and give you a point to click and drag on.
