It sounds somewhat artificial like it is distorted or too much compressed. In the Trailer it is the same, so it is obviously not due to my Soundcard. By the way it is a “Creative Audigy 2 ZS” with 32 bit resolution. The Speakers are “Creative SoundWorks MegaWorks 5.1 THX 550”. I can also hear it with headphones after a while. For me it is pain in the ears. Maybe you have compressed the soundfiles too much, or set the bitrate too low? I don’t know, what exactly the problem is, but it sounds really bad and my soundcard is not the reason. Of course I might play the game without sounds but then there would be absolute no atmosphere, that’s why I played XCOM
