Volume is too low for Narrative Content in Act IV

I've had volume issues hearing the lore objects and even Daresso's narration; the NPC will speak twice as loudly, but the narration is very difficult to hear - it sounds like it is playing back at 1/2 the volume. Would be nice to see this fixed prior to launch as it's very difficult to hear. Note this is even after messing around with the individual volume settings.
