I lost sound in my Tekken 7, and I had the brilliant idea to update the Realtek audio driver. I downloaded it from some damned website, updated it, and now my audio driver is completely gone. There’s no sound. Please help, I don’t understand what I need to download (I’m lost in that huge archive of drivers for my laptop, I don’t understand anything).

I’ve already find out how to fix ittt, I almost had a heart attack, oh my god
