I dont know if this already got adressed, but...
If you walk or sit or whatever, you can't hear the sound of footsteps direktly behind you 
please fix!
No stepsound behind you!
NO SOUND OUTSIDE VIEW. DEVS ARE FIXING IT:
Its adressed. Its because in Sandstorm they do not render enemies/teammates that is not in your vision.
That removed the soundscape as well and the developers know and are working on it.
@Pacalis yea i thought so too
but I didnt see it in the known issues so,...
Yeah, I don't know how that works, known issues is definitely not updated on everything. My source is the weekly Q&A on youtube, addressing questions between NWI and us all, but I'd rather have a complete log to look at myself, because the youtube Q&A is a pain to watch lasting forever and having repeating video loops and similar questions=)
