NPC Audio not playing, how do I fix it?

[Vinir]

I haven't played my latest save in a while and yesterday when I decided to get back to it I noticed all the NPCs voices were missing. All the other sounds are ok, music, audio effects, radio, etc. I'm not sure what or how did that happen, but I remember the last mod I installed was the Unified HUD project. Besides that one my load order's been the same since last april, and I was able to play the game with no issues back then. Is there anything I can do to fix this bug? I checked this forum and this question went unanswered for years.

 

I'm afraid that verifying the game cache on steam will mess up my mod files and my save, so is there anything else I can do?

 

Here's my load order:

On top of those I have the Unified HUD and Ojo Bueno's textures

Verifying the game will not mess up your mods.
