To extract the sound into the right folder when your map is played, you have to check the 'save full path'-box when you add it to a pk3 (with winzip or packscape). Of course the mp3 (or wav, whatever) has to be in the right folder so the path sais 'sound/music' when you check it 's properties (I 'm not sure if this is the exact path, I 'll have to check that) and not something like 'C:\Program Files\EA Games\Mohaa\main\sounds\music' -> that won't work cause the pk3 is in your main and so the path starts in your main.

Hope this helps ya.
