I deleted it from my computer, I rebooted the computer already a couple of times and the sound is still gone. I also tried to re-install the driver, but I don't know which one it is ( I only know it's a realtek audio driver), and each time i search for a driver, i download something which appears to be a driver searcher, than it tells me that I don't have a realtek audio driver and it says that I can download it, when I click on download, it says that i have to register myself and pay 30 euros. ( ps i'm from belgium so im sorry if my english isn't that good haha . )
