I'm getting no sound throughout the whole video, and youtube lists it as having music from a particular Debussy recording, which is then also unavailable (https://www.youtube.com/watch?v=vhogGOTnT9I)

Muting the sound is the usual response to streams and videos that plays audio that someone claims to own the rights to. Is this another casualty to how easy youtube makes it for copyright trolls (or people indistinguishable to copyright trolls)?

It plays fine for me, but it does have a 3D demo with some classical music at the end, so maybe YouTube disabled sound based on your location.
