If you mean Crash, InFlight, Intro, Menu, TakeOff music, i think for Un-modded il2 you have to convert your audio files to default format ( .wav 192kb/s stereo with sampling rate 44100 Hz and file attribute MPEG layer-3 ) and put them in respective folders in C:\Program\Ubisoft\IL-2 Sturmovik 1946\samples\Music
i.e. Crash, InFlight, Intro, Menu, TakeOff folders. For HSFX version no idea!

Whaaa? :OO


I'm talking about background as in picture
