HOMM8695: And where can I find the audio settings of the game if I had tried to put all the settings chosen on DOSBox? Also "Install.exe" (where he also had the audio settings of the game) in this version of your GOG, is not available, then to make matters worse I have the version of the Windows operating system to x64.
Like I wrote, there is a shortcut both in
Start Menu and in game folder ('Launch Settings'). Both point to setup.exe (not install.exe) where you can check / change original sound settings.
I know for fact it is included in our installer, as I just downloaded and installed it. Maybe you have one of the earlier builds, in that case, please just redownload the latest one from your account.
