Intro audio ignores volume settings

Bug:
In the intro sequence of a new game the audio ignores the volume settings.

Details:
The audio plays out in max volume despite any changes made to the volume sliders, from the starting scrolling text ("The Industrial Revolution ushered in a new era (...)") up to right before the conversation between Miriam and Johannes starts. This includes the sound effects of the cutscene where the camera zooms out of the moon into the ship and Miriam gets up from the chair and walks towards the camera (water/rain, boat creaking and Miriam's steps).

Occurrence:
Every time the intro sequence plays out and the volume sliders are lowered in the game settings.

Severity:
Just annoying

Reproducible:
Yes. By lowering the volume of the game in the audio settings then starting a new game and letting the intro sequence play out.

Here's a 1 minute video where I set the volume all the way down to 0. Notice that the Title Screen is silent and so are the menus and the dialogue as expected. Everything seems fine except for the sequence reported above.



Hope it helps.
