Bro, did you find any solution yet? I am having the same issue a year later lol. Game works fine on motherboard audio(but that is crappy) but as soon as I switch to my sound card, I can hear sound for a short while in the menu but after that there is no audio till I restart my PC. All other games work perfectly fine with no issues. I have reinstalled game, audio drivers, even onstalled a fresh copy of windows but still the same issue...
