I initially had the game installed on an external HDD. After 4 or 5 minutes of play the audio would become higher in pitch with an echo like effect to it.
This would occur every play session, reguardless of looking at cartographer, not ever having looked at cartographer, fresh boot of game, fresh booting of console, etc.
I eventually thought it could be related to being installed on the external drive so i transfered it to my internal HDD. I have not experienced the issue since.
Animals passive. All other settings default.
Have game installed on external HDD, play for 4 to 10 minutes.
