Dialogue volume fluctuating mid conversation

[LaughingMan.2405]

The volume of lines during the story changes multiple times per sentence, no matter which npc is talking. The change is gradual but rather quick. It usually starts out really soft, quickly ramps up to max volume, and then will fade. For longer lines, it tends to fluctuate. This is incredibly distracting and is making it hard to pay attention to the actual story.

 

I checked the Windows setting that automatically lowers volume when communication is detected, but that is already set to "Do nothing".

 

Anyone have any ideas on how to solve this, or is this how the volume is supposed to be for dialogue?

 

Should also add, I use a 5.1 surround sound setup, which I've had for 5+ years. No problems with other games or media.
