I am not exactly sure how to describe this issue I keep running into, but I’ll do my best. I will be playing, then all of a sudden the normal audio cuts out and a loud, terrible noise plays instead. Like a dial up tone, but worse. It will happen on the main menu mostly, but sometimes during game play. I turned the voice audio all the way down, which seemed to make it go away, but it still happens every now and then.
Hey there! Sorry for the delay in response.
If you are able to, could you open a ticket and share a clip of this with us over on our Discord?
