no audio device installed. I have tried all drivers including the realtek drivers from my laptop's website but it doesn't fix it. Could it be related to the reg file (disable drivers installation in windows update) that we open after running windows update after installing atlas? because before atlas I could use realtek drivers without any problem. I have installed drivers many times, rebooted and used ddu. the interesting part is that the sound and game controllers are also missing in the device manager. There is nothing related to sound in the device maanger.
