Fade in / Fade out works poorly at the beginning.

The fade in feature does not trigger correctly the first time a track is played. Interestingly, the fade works perfectly on the second playback all good. 
I’m currently investigating the cause and plan to work on a fix.

**To Reproduce** :

1. Load the application.
2. play an audio track.
3. Observe the initial fade-in (glitches/fades "weirdly").
4. Stop and play again (fade works correctly).
