Probably say3d can be used. It will stop the sound if the object it's attached to is destroyed and it will follow the object if it moves around.

This commit broke it by introducing random delays that are calculated on each machine independently:

Just need to remove these random

Because the function runs on every machine, everyone rolls a different number.
Sound and explosion is done by the server, but visuals by everyone (since related commands have local effects).
