I've tried all following WITH NO SUCCESS: There is no sound after the intro videos. I bought GTA5 few days ago via steam, installed it and I'm able to run it with no issues except of SOUND. I know there were already many questions regarding this issue online but I wen't literally through all links, articles, forums I've found on this topic reddit, steam support, rockstar, nvidia, you name it. Not sure if this topic fits here but I'll try anyway.
