I'm trying to play the original version of Baldur's Gate but for some reason ambiance music sometimes doesn't work. It happens when I enter a new area, for example, when I enter Candlekeep's Inn, the Friendly Arm Inn or the nearby temple. I have tried to install the Unfinished Bussiness mod and tried the game in two different computers (bot with WIN 10) but the problem still persists. Does someone here know how to fix it?

In the original the music is not looped (outside of combat) and sometimes can be interrupted. It should not happen all the time when you enter a building, it should be rather seldom. From what I observed, saving the game (not by quicksave) also interrupts the music. The music should play when you reload the game, or exit and enter the building again.
