I might help explain some things
1. Realtek HD Audio device vs a Realtek Audio Codec
The High Def (HD) audio standard requires both HD controllers and HD devices. The HD audio controller connects to the PCI bus. One or more HD audio devices will connect to the HD controller
PCI Bus <====> HD audio controller <=====> one more HD audio devices
- Starting with Win 8, MS includes a generic driver for the HD audio bus controller
- Realtek (and other vendors) provide drivers for their HD audio devices that connect to an HD audio controller
- Vendors may also provide their own driver for the controller but have rarely seen this occur
The Realtek HD Audio device drivers are for their devices that connect to controllers. If you have HD audio, you can see device relationships on your own PC using Device Manager. Click View->Devices by Connection
Showbiz has a Realtek Audio Codec (its name first appeared when first posted the driver details snapshot). The codec is not an HD audio device. It would appear the codec works with / augments the onboard Intel SST audio . (Given the architecture, Hardware names and IDs I see from showbiz, i also don't believe showbiz's PC is HD audio.) You can find the Realtek relationship defined in showbiz's Speccy
You had problems installing the EXE file from Dell. The Dell EXE includes more then just the files needed for the driver (see below) If all is working now, leave it as is. Don't bother with the EXE
2. The word "driver" is an ambiguous term
It's commonly used by everyone to refer to the "driver package" as well as the "driver installation app". The "driver package" is the set of files needed to implement the h/w interface. The driver package always includes an INF file. The INF tells Windows how to install the driver files. Only the driver package files are saved in the Windows DriverStore.
An EXE file is a driver installation app. It will always include the package but can also include software apps, it might provide the user a GUI interface, and more that wouldn't be in the package. Catalyst Control Center is an example of a s/w app that gets installed by the EXE along with the driver package. When uninstalling a driver, one should always first check Programs and Features because if the driver was installed by an EXE file, the vendor may have also provided an uninstaller for you.
