Or ist there any ini or such where I can tune the individual loudness of sounds ?
In the Constante folder you'll find a file Sons.txt which is the ini file for the sounds.
The format is easy to understand, but the effects of changes aren't. The lines you'd be most interested in are:
20 2 1 F 1600 musket1
21 2 1 F 800 musket2
22 2 0 F 1600 canon04
23 2 0 F 2500 canon08
24 2 0 F 3200 canon12
The first two are musket sounds and are there just for comparison. The last three are the cannon sounds.
The volume is the large number, 800 through 3200. You can also see in the file where the horse sounds are in the 300 to 16oo range.
Unfortunately, the volume doesn't work quite the way you'd think. The sounds themselves are played at full volume at the source, and the number is the distance where the volume drops to zero. You can edit the volume of the original sound in Microsoft's sound recorder, in XP it's Start->Accessories->Entertainment->SoundRecorder (just be sure to save a copy of the original) . You can change the numbers in the file, just remember that a small change can make a major difference, and some sounds might get dropped. Getting a good balance is difficult. In my experiments with a different game, the sounds were either too loud, heard too far away, or not there at all.
Good luck.
