So I'm playing through the game in the enhanced edition (completed it once in the vanilla version) and I'm at the tail end of the Hiberheim quests, shortly after taking down Boreas.

And...all the voices are suddenly gone! The subtitles appear, but both the combat quips and actual npc dialogue is completely silent. No voice acting. I tried reloading an earlier save, and I realized it's the whole game; no matter how far back I go, no one has voices anymore. I didn't do anything between my play session last night (it was normal) and booting it up just now.

Anyone have any ideas on why this is happening or suggestions? I don't wanna abandon my playthrough but this it's un-natural this way.
