Despite all of my efforts I can't get certain soundtracks to play properly. The best example is during Alduin's Bane quest. There are normally two tracks of music that should play, a short one when the Nord heroes banish Alduin using the Eldar Scroll, and a longer one when you face Alduin in combat afterwords. Yet for me, neither will play and this moment in the game isn't as epic as it should be. If load the autosave taken after you return from the past, the regular dragon combat music will startup, but not the special track.

Does anybody have a fix for this? Reloading, restarting Skyrim, restarting my computer, adjusting my audio settings, none of these seem to do anything.

I am currently running the latest non-beta Steam version of Skyrim.
