[v18.3 Ground Combat] Sound queue plays at once on window focus

[irongamer]

This has made me jump quite a few times over this weekend.

I'm playing the game in a window. On a terror mission I'll move my guys and hit end turn. Before the enemy turn is over I'll click outside the Xenonauts window in my other monitor and read something. The Xenonauts window loses focus at this point. When I click back on the Xenonauts window and the application once again has focus it sounds like many, if not all, of the sounds from the enemy turn play all at once.
