Yes I've tried rebooting it. In the properties general tab it says that there is no driver installed. In details it says that the device is on the High Def Audio Bus. I've tried to update the driver and it says that it encountered a problem and that the device attached to the system is not functioning. If I look under System Devices/ High Def Audio Controller / General Tab says device is working properly / Driver Tab I try to update it and it says driver is up to date.
The driver we're trying to fix isn't under System Devices, rather it's under Sound, video and game controllers. What do you see there?
