@SoyKappy it seems to be a vanilla game issue, as I’ve tested it on a Steam copy and it still happens both on Steam and Plutonium. So, not exactly a Plutonium problem, but it would be nice if they fix it.
T5SP on Plutonium also has a problem with not having audio devices connected, but it doesn’t happen on the vanilla game.
@Corza_iaM either connect an audio device or try an audio mixing program that like Voicemeeter.
