This may be a BIT off topic but the really smart guys hang out here so here goes..
Here is the [sound] section of my FS2002.cfg file:
Most of my planes sound great BUT the ones from Arron Swindle and others ALL sound terrible and in the same way, they sound like they were recorded in a tunnel. Now as many files as he put out I can't believe I would be the only one to think they have a problem so I am inclined to think I may have a config issue. By the way, the new China Clipper (B314) also sounds terrible. The DF737, Archer, PIC767 and all the default MS planes sound great.
Any clues/hints?? I am using a SoundBlater Live V 5.X
