All other sound effects in-game work fine, but for some reason the only music that plays is in the opening intro. Can someone help me out, i have no idea whats going on.

Are you playing the GOG version without any patches? GOG version uses mp3 music, and patching it might cause the game to expect music from CD.

Can you actually play the music mp3 files outside of the game?

Also, if you go to Options and Audio, did you try turning the music slider all the way up?

Hey, thanks for the reply. Im not sure if it's the patched version or not, but i am able to access the mp3 music files, which only work when the game is not running. I've tried changing the audio options in-game, and setting the music slider to max, but nothing seems to work.

Sorry, no idea then :( Try contacting support.

I play it on Windows 10 and have no Music too :(

Someone wrote somewhere to have VLC media player active in the background and it apparently worked. I have not tried it myself though but will try that next time I install the game.
