Game problems reports and questions

[too-cool]

I have un-installed and re-install IL2 1946 more than 5 time in the last 5 days trying to isolate a sound problem. The problem is that every time I start / stop IL-2 and select a aircraft from arming when I start the a/c I may or may not have engine sound. Sometimes I'll have engine but it will come and go. Most of the times I lose the sound when the engine is between 1500-2700 rpm but sometimes I'll lose it between 500-1500 and it may come back in at 2000 or 2700. I have 4.091bm aI have UN-installed and re-install IL2 1946 more than 5 time in the last 5 days trying to isolate a sound problem.

I have 4.091bm and .93 sound mod installed. I'm using a unified mod installer created by the 352ndvfg. No on else who has used the installer has had this problem. I'm attaching a pdf to show the error reported by 7 zip(rar) when extracting the file parts to my IL-2 Dir. Some time I can restart the game all the sound are all OK but not every time, thats the funny part is that it comes and goes at difference rpm ranges. Also 352ndvfg is using the latest mods is there unified installer. My system specs. are
