When trying to install "Analog Devices ADI 198x Integrated HD Audio" drivers for my Dell Optiplex 745, I ran into an issue where the installation stops after giving an error message "HDA audio bus driver is required and not found".
There were not many articles on how to fix this issue. Finally, I came up with two simple steps to fix this issue.- The issue can be resolved by applying the HP patch SP33867. You can download the Microsoft Universal Audio Architecture (UAA) Bus driver for High Definition Audio from here. If you have any issues with the first link, you can also download from here.
- Download the "Analog Devices ADI 198x Integrated HD Audio Drivers" from http://support.dell.com/. Direct link for this driver is here.
Please post in your comments, suggestions and questions. I'll try to respond promptly.
