I did not notice any audio artefacts while playing ToT, but I did encounter a new weird sound post update. I already forgot where it was, but I think it was master writ turn in related.
Edit: yes, its was master writ turning in. Heard it today again.
Thank goodness someone else commented, i thought I was developing hearing issues. There is an echo on every action throughout the game as if its being triggered in the ambient background sounds, very annoying once you notice it.
I also had some weird sound when I successfully excavated an antiquity. Still not hearing anything out of the ordinary with ToT though (or may be that particular change is not really bothering me, so I'm not registering it).
