Sound issues with 5.1 channel speakers!

[뭐래니.June]

My 5.1 speakers worked very well with original Doom3 since it has sound channel options.

However, in BFG edition, the sound is so unclear and hazy.
Just imagine an imp appeared from your left side and coming to you.
For me, it sounds like the imp is still far away since it sounds too small
and I cannot notice the imp showed up because the sound is too small
and I cannot feel the imp is coming because it sounds too small !!

Interestingly the sound from intro is pretty good.
So I guess the sound setting within the game must be issued.

Obviously my sound driver is fine and speaker channel is set as 5.1
and working well which is confirmed by other games.
Anybody has good ideas?

Damn at least orignal Doom3 had doomconfig.cfg by which I can manage or
optimize other options but not BFG...
I really cannot understand why the developers removed those optimizing options...

BFG has config file too. Drop down the console and see s_ cvars (or snd_), maybe there is something useful there.
