Original Saga Music problem

Hey guys,
Now I know this is the Enhanced Edition forum , so forgive me for asking this here but since I completed the game with EE around dozen times I decided to fire up the old original Baldurs Gate for the nostalgia.
After playing little I noticed a problem where the background music does not play at certain times when it should be.
- The music does not play in the background when entering any temple, instead of playing this:

All I get are just the footsteps of my party
- The music does not play in dreams, here watch this video

As you can see there is music in it, but in my game only the narrator's voice is heard
No mods are installed. And the game is always run as administrator.
Sometimes there is also no battle music.
Does anyone know what might cause this issue and how would I be able to fix it, it feels pretty dull to play like this.
Specs:
Windows 7 x64, Original saga is from GOG, the sound 'card' I use is onboard (Realtek ALC898 Audio Codec)
Thanks in forward
EDIT: I forgot to mention, but the 'Environmental Sounds' option is disabled and greyed out and I can't check/uncheck it.
Also I play the game while using the 'Q' quicksave button a lot. This tends to usually reset the music from the beginning so I'm not sure if this might cause any problems.
