Audio 7.1 does work. My PC doesn't recognize my headphones. I've been trying stuff for the past 3 hours and I'm about to give up, throw this headphones in the trash and buy and actual good set. I desperately need help. I tried all support stuff, none of them worked. I tried to reinstall the drivers, didn't work. And i refuse to reinstall Windows. This is now at an absurd point that I've tried everything and nothing works. Please fix your software or give me actual help. Don't you dare send me a support link, believe me when I say I already tried like 20 of those.
