I have an issue where I cannot hear any dialogue in the actual character to character cutscenes.

Combat banter? Audible. Random banter walking around? Audible. All spell effects, movement sounds, jumping noises etc... Audible. Want to talk to any NPC with their own dialogue? Completely mute, no dialogue happens at all. This is happening in both single player and multiplayer games, across all of my saves (new ones included). Their mouths animate for the conversation, the subtitles are visible, but no audio comes out within conversations.

I've triple checked my settings, verified integrity of game files, uninstalled and reinstalled the game. I'm at a loss as to how to fix this or even start. Has anyone else experienced this?
