Soundless func_tracktrains?

So I had the pleasure of seeing the map I just released on a server
today. Server was empty except for someone idling, but I ran
around for a little bit to check it out.

Seems the sounds that I have for the func_tracktrains are not making
noise when the level is running on a server. There is a train
that has a horn sound as the start sound and a train moving sound as
it's moving sound. There's also an elevator that makes elevator
noises when moving and does a "Ding!" when it stops. These are
all HL2 sounds, nothing custom.

The func_tracktrains make noise when I load the map up on my
computer. The people who have run the map have told me that they
hear the noise as well. However, when I tested the map out on
someone's server before I released it I also noticed that the
func_tracktrains were not making any noise. We thought that maybe
it was server specific, and I asked around a little bit and no one knew
what I was talking about.

Is this a problem with the HL2DM server code? One possibility
could be that the sounds are in different directories on each computer
because of the different Steam user names, but this theory is a stretch
considering that would apply to textures and all the other sounds you
hear in the game. Pretty aggrevating and I have to say that a Big
loud lumbering train is much more intimidating than a silent model
floating through the map.

Was there a "Play in multiplayer" flag on the sounds or something similar maybe?

maybe your going deaf?i had the same idea as myrk but i dont wanna
steal his answer = P i guess thats what happens when one doesnt put
"this is an answer to a problem

No, I'm not going deaf. I listen to music loudly, but I can still
hear. And there is no sort of flag that specifies whether the
sound plays in multiplayer. The sounds are not a seperate entity,
but are plugged into func_tracktrain properties. They work when
you load up the level alone, but not when it's on a server and you join
to play. So strange...

i remember there were issues in hl for multiplayer train sounds - there was a tfc map where the train noise could get stuck "on" even when the train was not moving.

You could perhaps create an ambient generic and specify the source entity to be the train.

Under func_tracktrain outputs specify triggers such as on move, on stop etc to turn on or off the correct ambient_generics.

Well, the maps out there so I'm not going to bother trying to work
around it. I'm convinced it is a bug. Like I said, the
sound works when loaded by the client. But when loaded on a
server it does not work.
