Playing a sound that every player hears at once?

What can be used to play a sound that everyone on the server hears at the same time, same volume preferably?

or

Try this out:
[lua]
BroadcastLua( ‘surface.PlaySound( “PATHTOSOUND” )’ )
[/lua]

WorldSound is nil in Garry’s Mod 13, I thought?

surface.PlaySound is your best bet! – Garry also removed the restriction of 2 sounds playing at once it seems.

That works perfectly. Thank you everyone.
