The sound of wind passing by the elytra wings has been removed during flight. All my audio settings are on. Flying with elytra is no longer satisfying, and it's just super quiet. I feel like when 1.16.210 came out, there was still elytra sounds. Just now I'm noticing they are gone. If it helps, I was flying with elytra in creative mode. (Of course with the wings deployed/opened)
