Timeline AudioClip ease not working

Hey there,

i am trying to get an AudioClip that i use in the Timeline to fade in / fade out.
The Track is associated to an object with an audio source.

As you can see in the screenshot, i got the easings set. But in the game, the clips just starts and ends abruptly. Any idea how to fix this?

I am also using SteamAudio as spatializer, but i hope that is not the reason.

How long does the clip play, until it stops? And is it always the exact same point, the audio stops?
