Please disable the Sunken Hideout "moving stones" ambient sound

There's a background sound in the Sunken hideout, I don't know what sound it is exactly maybe moving stones, but it gets very annoying after a while. This is with the default audio settings : https://youtu.be/jmsoK5mQqf8

It's possible to disable it by completely turning all the sounds effects off, which is not practical if you want to keep them while playing. Please turn it off, thanks.

+1. I think it's simply this thing in the corner and I can't remove the decoration. https://imgur.com/h6GVNc2
