 ## Audience operations are not fully supported
 
 Velocity currently does not support all Audience operations of the Adventure API, so these operations should be handled on the backend.
-Furthermore, playing sound was previously considered infeasible, as for versions below 1.19.3, a registry of hardcoded sound IDs is required.

+[^sounds-note]: Playing sounds only works on 1.19.3+ and requires an emitter ([`Sound.Emitter#self()`](https://jd.advntr.dev/api/latest/net/kyori/adventure/sound/Sound.Emitter.html#self()) or another player from the same server). [`Player#playSound(Sound)`](jd:velocity:com.velocitypowered.api.proxy.Player#playSound(net.kyori.adventure.sound.Sound)) is not implemented, as Adventure's contract requires sounds to play at the player's current position.
