[2023] Any other PS4 players experiencing issues with sound?

I can speak to the audio bug a little. A fix is going out for that in the next update. A performance improvement went out that was causing consoles to potentially run out of memory in a rather... 'ungraceful' way, if you had a certain arrangement of people in the city/islands. We weren't able to reproduce it in the studio on development builds, even after we started getting reports on live, so it made fixing it challenging. I tracked it down and we've fixed it thankfully, sorry it made it's way out to you.
