Hey, I've configured the script for the server I'm using it on but it won't play sound files, could anyone help please? The configured script:
https://gist.github.com/consgames/41d34d921007817ff633f16fa59c851a

Thanks.

I couldn't get this work with the current version, I set the channel name and server and mp3 file and nothing
