[0.15.20] Sounds/Music does not resume after research screen

[Dragonmystic]

Windows 10, 64 bit.

Here are the steps, as best as I can remember.

* Had an open inventory screen.
* Was zoomed in nearly to full on an area.
* I believe a background music track had just ended, or was about to end.

* Research Finished, tech tree popped up.
* Spent a while in the Tech tree. Scrolled my infinite mouse wheel a bit.
* Selected a research.

* No sounds at all were active on return to the game.

Going into and out of a menu fixed the issue.

Edit:
Just got it as well when laying down rails and an auto-save popped up.
