All of the voices for the 3.1 main scenario are very distorted. I opened up an in-game ticket but just wanted to post here incase anybody else was having the same issue. The voices are very faint and sound as though they are all talking underwater. The first time I noticed it was in Matoya's cave during a cut scene, and the voices were so faint I thought it was background aetheric voices in Matoya's cave that I was hearing.
