Your Own Jump Pad Sounds Do Not Play Online
example: cduel1_.wad on DTX1. Simply join the server and use the jump pads. You will notice no sounds play even though they are supposed to. Weirdly enough you can hear your enemy's jump pads.
That's because server version of S_Sound() (all overloaded variants) does nothing at all. It's just {}. S_Sound() is called form PCD_ACTIVATORSOUND case in DLevelScript::RunScript.
