I assume your using Unified Installer Version 1.0

go to

Code:

C:\Program Files\Ubisoft\IL-2 Sturmovik 1946\files\presets\sounds

and look for a sound file called "motor.Jumo213.prs" this is the sound file thats causing the problem.

move this file somewhere safe, e.g. desktop, and copy another sound file, say motor.Jumo211.prs and rename it to motor.Jumo213.prs

You should find that the D9 Dora's and MrJolly's FW-190-D11 & FW-190-D13 (if you have them) sound levels are now at a more ear friendly level

Hope this helps
