To be honest, the game´s soundmix is pretty unbalanced. The music is way to loud, the voices way to silent and the effects are okish at best. I would turn it on 3, but then i barely hear anything what the NPC´s are talking. If i put it on 5, the music blows my head away. So i leave it on 4 and turn of the music completely, whats a shame. Would be great if the team could implement seperate settings for Master (what it is right now), Effects, Voice, Music and even Ambience for the audiophiles out there.
