If you mean the audio that plays when the message itself is played that has been messed up for a while. The links still respond to the message correctly with their tight beam octal audio last i checked. (the ones with only 2 messages usually point at human stuff, and the ones with 3 messages seemed to point at structures still. Which is generated seems to be dependent on the structure as far as i can tell.(I have only repeatedly tested a small handful of thargoid structure/link messages.))
