Solution
Instead of adding the audio clip to the timeline
Create an empty GameObject with AudioSource Component added
Set the Audio Clip you want to play as the clip for the AudioSource
Make sure PlayOnAwake is ticked
Disable the GameObject
Drag the GameObject into the Timeline
Create a new activation Track and Clip
