I have two audio bugs. One worse than the other.
The first one is that characters sometimes speak more then once and stops saying what he is saying half way through. This happens quite a lot, but isn't influencing gameplay, just a bit annoying.
The other bug however, is worse and the game becomes quite unplayable after a few seconds. The bug is that all audio keeps looping and looping and it will start to make a lot of noise. This happens to me every 10-15 minutes or so.
Most often the audio keeps looping in the menu as well, which basically forces me to restart the game.
