Latitude E6520 - High Definition Audio Controller error 43
Hello everyone!! I own a Latitude E6520 and I realize that many times when I start laptop the device with name "High Definition Audio Controller" faces error 43. The path for this device is the following: Device Manager -> System devices -> High Definition Audio Controller. If I restart or, delete device and then directly press the button "Scan for hardware changes", the device will appear again without problem. I realized that when problem occurs, the NVidia HDMI soundcard disappears, and appears again when I make the actions mentioned above, so this has to do with NVidia. My installed OS is Windows 10 RS5 and I use NVidia drivers Quadro Desktop/Quadro Notebook Driver Release R390 U8 (392.00) WHQL Release Date: 2018.9.5 and have installed the latest BIOS A22. Does anyone faces same problem, or have any ideas for fixing the problem permanently? Are there any other drivers that should be installed instead of W10 drivers for the device that faces error 43? I would like to thank in advance everyone for helping, and taking part to this conversation.

I solved the problem almost two years after making the question here.
I disabled NVIDIA OPTIMUS and problem disappeared!
