I'm afraid I could never get it to work properly with Exile, so in the end I gave up the whole project. Both mods seems to work perfectly fine without Exile, so we can assume that it's probably a config conflict. And if I had to guess, the error probably lies within CfgMusic or CfgSounds. But I never got further than that, I just set up a music bot for the voice chat instead. (Discord, that is, since we don't use TFAR/ACRE)
