Yes, I'm aware of it too. When I launched the game for first time, there was no audio. Needed to select the audio device in the game. And later when I had no audio again, I had to select the wrong device and back to correct device. But now it seems to be working, even without commandline options. There is definitely something weird going on. That happens if you launch a game on a platform before testing it. Especially disappointing if there was a dedicated Beta phase for testing months prior launch… Sorry, I can't get over it at the moment.
