Dialogue Audio Gone During Cinematics
I would check your audio settings and see if your system is set to use 7.1 surround sound. Unfortunately, GW2 doesn’t support it right now so if this is indeed the cause of your issue you can switch to a smaller number of channels and the dialogue should come back.
Yea, I checked, I don’t use 7.1 surround. Is there anything else that might impact it?
This is something that impacted me during seemingly random portions of dialogue also. Was most noticeable during vigil storyline for me, but I recall instances of it happening in general personal story cinematics.
