Round end "Win" music
To put in your own sounds.
Go to this location:
C:\Program Files\Steam\steamapps\steamuserid\day of defeat source\dod\sound\Ambient\
If the folder Ambient does not exist, create it. If neither folder exist you can just create them
Edit two MP3 files. By edit them I mean make them small in size, maybe 5 or 10 seconds at most, you can also reduce their volume in an audio editing program such as Nero Wav editor.
Name the files us_win.mp3 and german_win.mp3 and save them to the Ambient folder.
(you can also record 5 seconds of silence if you dont want any music at all)
Now you will hear these files rather than the insanely loud end of round music you normally hear.
This does not overwrite or replace the original win music, if you change your mind just delete the 2 files and it will revert to the gawdawful standard.
I've attached the files that I now use, they're just 10 seconds of silence.
