I downloaded a plane that had instructions on how to turn the sound quality up, in a .cfg file for FS2002. I also found a line that said something like 'Speakers=2", and changing it to speakers=4 led to surround sound. However, I cannot find this again, nor the instructions on how to turn the sound quality up again. =\
This isn't that important as my motherboard died and is on RMA, and my onboard sound was 5.1. I would like to know how to do it for when my board gets back.
