I don’t have problems with the launcher or installing. I hear the two drum beats after the patcher finishes and is ready to launch the game but after that the game has no audio. No voices, no music, no effect sounds, nothing. The game does not appear in my volume mixer. I am using a Corsair Virtuoso headset and everything else that has sound is working fine. Let me know if you need anymore information from me.
Have you tried modifying everything in the “Miscellaneous” section of “Audio”?
