Are you running amx? If so the link to get sounds to play is here. I highly recommed this plugin. http://djeyl.net/forum/index.php?showtopic=3440&hl=pd_sound You will also need a plugin to upload the souds to a client.Or you can put them as a zip file on your website. You can add as many as 40-4...
You can set gravity in server.cfg or in amx_cvar menu. Make sure to tell any admins that setting gravity to high can crash a cs server. I haven't tried it on cz server. I find plenty of other things that can crash my server
