After a clean install my realtek HD audio (integrated in mainboard) doesn't install correctly. It's listed under system devices with a yellow triangle. The realtek drivers could be installed fine before the clean install, but not anymore. If I search for the driver manually in the folder it says there are no new drivers there, but I'm sure they are. I've already tried uninstalling the device and trying again, but it doesn't work. It is enabled in bios. Any ideas why it suddenly doesn't work anymore?
