I’ve been having exactly the same issue on 4.25 recently. It started to occur after I deleted a bunch of assets. I now get the same warning you do. Are you using material instances by any chance?

I was recently dabbling with material instances and seemed to have issues deleting / replacing assets. Since your sound obviously isn’t a reference, it’s doesn’t seem likely to be the cause.

Not for the sound but for the material yes.
