Microsoft Bus Driver should be loaded in your system before installing Realtek HD Audio Driver
Looked into a few sources and I thought the solution could be clearer.
To fix this follow these steps
- Open device manager in system properties
- Find a PCI device in the System Devices section that has a yellow exclamation mark next to it
- Right click on that device and click Update Drivers. This will install UAA Audio Bus.
- Proceed to install Realtek HD Audio Drivers.
