I'm doing the Staff of Magnus quest, where you have to go to Labyrinthian and retrieve the staff of Magnus. It's been all fine and dandy, but the mysterious voice, that drains your magicka, has no audio (or subtitles, for that matter) just before Labyrinthian tribune part of the dungeon. Has anyone else had similar problems and if so have you been able to fix them somehow?

I've had the same problem. The last three instances just drain my magicka - no voice, nor any other related sound.

I am having the same proble. Plus the ghosts that are supposed to supply the backstory have no dialogue. They just stand there and look at me. I hope I didn't miss anything.

Second!

I have the same problem.

I've noticed this a few times when I enter Labryinthian from an unusual direction (like, from over the hill behind the entrance to the crypt). There may be quest triggers at the 'normal' entrances to Labrinthian that are needed to set up the ghosts.
