I think the sounds are like mohaa elgbots client needs the sound files to hear it, testing something out now will up date this post when I know something more.

With a mod you have to set +set fs_game mods/gungame and players have to down load the mod.ff and gungame.iwd, doing it this way there is no downloading to do, because it's server side with nothing to download. The only down side to not just running the complete mod is it runs off of dm.gsc so you can't switch gametype to plain dm match. I've tweeked it a bit and added a seperate message.gsx because the message.gsc from the mod made a repeting console error, which didn't effect the game any but I didn't want it to spam my console logfile. I never got to see if the music was working or not never paid attention to it, i know the" admin_tools.gsc" doesn't work because there is know "menu" that part of the mod is in the mod.ff so without that some things will not work.

Now something else I learned you may or may not know is with the codx patch you can add files localized_english_iw07.iwd or just make a folder called "main_shared" and put your scripts in that. The good thing about using a main_shared folder instead of a .iwd is you can edit the scripts and not have to upload the .iwd file every time you need to tweek a script.
