// TODO AUDIO PREDICT Figure out a better way to handle sound and prediction. For now, this works well enough?
//
// Currently a client will predict when a door is going to close automatically. So any client in PVS range can just
// play their audio locally. Playing it server-side causes an odd delay, while in shared it causes double-audio.
//
// But if we just do that, then if a door is closed prematurely as the result of an interaction (i.e., using "E" on
// an open door), then the audio would only be played for the client performing the interaction.
//
// So we do this:
// - Play audio client-side IF the closing is being predicted (auto-close or predicted interaction)
// - Server assumes automated closing is predicted by clients and does not play audio unless otherwise specified.
// - Major exception is player interactions, which other players cannot predict
// - In that case, send audio to all players, except possibly the interacting player if it was a predicted
// interaction.
