You can use the Amboy Tactical Tool to attach a certain sound/music (sound file) to specific messages in textbox. For example I had for some time a short music file with a "victory!" feel to it, it played every time I levelled up

However, this tool is not working at the moment, one of its values needs to be changed with (it seems) every single changelog, and as far as I know the only one who is able to know what the new value is, is the author of the software
