Hello @triquetratrip and thank you for the update!
I just checked your video and honestly I haven't seen anything similar to this one before! It does look like a corruption of data, to be completely honest with you.
Can you please perform the troubleshooting steps listed in this article? Secondly, can you please reinstall your game? These steps will help you to eliminate any potentially corrupted files that can lead to this sound issue.
If you're still experiencing this after performing all of the steps from above, can you please confirm if you're experiencing this issue only on this save, or multiple saves? Also, can you please make sure that you upload your recent save to the cloud?
Many thanks and if you have any additional questions, please let us know!
