Hi!
Same problem here - music doesn't change aboveground - it's playing only 2 track all the time aleroth theme and wilderness (i suppose) theme - certainly no farmland, inn or barracks music.
I tried to swap the "sound" folder with the one from the CD version but with no effect. Lowering the sound acceleration also doesn't work (it's not that old game so it's not the case anyway).
Maybe they broke something while upgrading from 1.04A to 1.05A version - there wasn't any cases like that on the forums before from what I know so maybe 1.04A wasn't broken.
Hope they will fix it with a new patch. Too bad I bought GOG version while having the CD version already
