It does (ok, one catch: if there's an atmosphere), sound has physical nature. The trick is in asking whether music/art/languages exist after any sentient life is gone

Can't sound transfer through the casing even if it's not vibrating air in the process?

No, there is a well-known experiment: take something that produces sound, put in a glass, suck air out. Won't hear a thing
