I have another sound problem that worries me quite a bit - especially, as nobody else seems to be haunted by it:
All my narrator sound tracks (in the intro cinematic, the narration during map generation, all tech quotes and the advisor lady) are reduced in loudness and barely audible at all. Everything else (music, sound effects) works perfectly fine.
I already switched from German to English without effect. Currently, I have dialed down everything but the voices and then increased then speakers up to a very high level. Now I can at least understand what they are saying, but the voices sound hollow and muffled.
Could this be related to the same thing? Are 2K and Firaxis aware of this, too? Or am I indeed the only one with this issue?
My sound comes from the on-board sound chip of my Asus main board (I don't have the type at hand, but will attach it later).
What I have done, though, is to delete the additional sound optimizing/enhancing program that comes with the main board, as it interferes with 'Voice Attack', a program that is essential for other games I play. (The deleted program is really just a mixer, not any sort of necessary driver or another essential software.)
