This zip file contains two (2) "sound.cfg" (sound configuration) files. By default, the "sound.cfg" file will produce a realistic interior cabin wind noise which some flightsimmers do not like. The "sound.2cfg" DOES NOT have default wind noise:
If you don't want the wind noise, do the following:
A: Open the aircraft's "sound" folder
B: Rename "sound.cfg" to "sound.1cfg"
C: Rename "sound.2cfg" to "sound.cfg"
D: A Windows Warning box may appear saying, "If you change a filename extension, the file may become unusable. Are you sure you want to change it?", Click "Yes"
For additional file details, see the "Notes.txt" included in this download.
