I recently picked up Jaws of Hakkon and started up a new game again. I'm in the same boat. I downloaded JoH and the 2 multiplayer packages, started 2 games, both have had almost no background music aside from battles or triggered events. That goes for the banter as well. Every is just silence aside from triggered "This area looks dangerous" type statements.
Edit. On a PC. Also, paying more attention I've noticed that the background music does play one loop as I load into an area. Once it completes the loop, I do not hear it again until another area (going through a transitional door for example) is loaded. I've heard the random banter during that initial loop, but once it ends, I do not hear it again.
Further testing, I've noticed during the loop if i open any menu, game or loot, the music sometimes comes to an abrupt end and I don't hear it again until another load.
On a side note, I've notice my followers seem to freeze as well as my controlled character (happened to be my inquisitor) froze in that "avatar placement" stance with arms out to the sides after a battle begins or during battle. The only way to break it is to take control of the character and jump.
