No sound in uploaded DLC

[Fishkiller]

Hi guys! Tried to upload several DLC from list #32 , but when I go through 75 input, Furby makes moves, shows something in the eyes, but without any sound. What am I doing wrong?
I upload DLC going through all steps described here in docs. It uploads successfully, I got 3 for slot in the DLC debug list. It shows new moves and graphic, but without sound :(

I ran into the same problem too, tried it on three different machines (Mac, Raspbian Buster and Stretch respectively) and can get many things in the fluffd-client to work along with successfully uploading DLC, but only get animations / graphics with any DLC you feed him, no audio. Read the docs up and down, tried the listed DLC there, and even tried custom DLC that ctxis's tool outputs, but no dice.

I then played through the Furby Connect app to download a song and study the upload in the debug menu to see if there is a particular combination of dlc uploaded needed, but the app wouldn't let me download anything. Upon further hunting, one YouTuber suggested that Hasbro is no longer updating the app and has pulled all the downloadable stuff (through the app, anyway). I wonder if there is something in the connect app that enabled DLC audio that can't be activated now, but that's pure speculation on my part only.
