I couldn't agree more. I am sure you are aware of this, but Sound and Audio are of high importance and could make or break a real gaming experience. So far (maybe because it is still alpha) the audio & sound-effects are not rich in colour.
The sound engine and features are quite linear and 'bland' at most times. Like the author said, there are no differences in audio quality and richness when characters are in different environments and surroundings.
Hope this could be fixed because it would create such an immerse experience to an already impressive gaming display.
