I've got a map here that doesn't appear to work well under Linux srcds..

(feel free to try it, great map..)
However.. Theres a giant diesel train in the map, and it's completely silent if it's played on a Linux server. Sounds fine in Windows srcds, from what I understand.
Has anyone else ever heard of this kind of problem? Or have any information about it? I've googled until my head fell off, can't find anything on it.
