I thought i was the only one, UC3 is abnormally loud in volume to me, in other words when I switch from playing another game or watching TV I gotta turn the volume waaay down because the music blasts through my house.
Then while I'm waiting for a match, I will here Cog and friend mumbling about an update that happened 3 months ago, then all of a sudden hear a blast of dubstep ringing my ear.
I think it's the videos. They don't have equal volume. Basically I just turn it off because of the inconsistency.
