Win 7 x64: Realtek Audio Driver Installs but High Definition Audio Driver fails?

Recently upgraded hard drive to an SSD and did a clean-install of Windows 7 using Dell media. Post install, I cannot get the audio working. Device manager shows ...

Bluetooth Audio Driver
High Definition Audio Device (yellow exclamation point)
Realtek High Definition Audio

I have tried the following to fix:

1. Uninstalling and deleting the driver then re-downloading using Dell Detect
2. Installing the RealTek R282 driver from the RealTek site
3. Windows Update does not find the driver
4. Right click on entry in device manager and letting Windows find it
5. Installing it manually from the Dell site

Any help is greatly appreciated and thanks in advance.
