Dolby Driver Mismatch - LONG time problem
This problem has gone on for months!
This is a special built machine, so I have no manufacturer to go to.
The exact error message is "The current Dolby audio driver version is 7.2.8000.14, and the software application expects driver version 7.2.7000.7. Please install a valid driver and software application combination." This occurs every time I start Windows. My basic sound functions still work, in contrast to some of those who also report this message in various forums.
I have Dolby Home Theater, shown on the All Programs menu as "Dolby Home Theater", "Dolby Home Theater.lnk", target "C:\Program Files (x86)\Dolby Home Theater v4\pcee4l.exe".
In Device Manager, Sound, video and game controllers I show "AMD High Definition Audio Device" and "Realtek High Definition Audio". The AMD disk shows "Driver Ver 12-130", properties, details, shows "Driver Version 126.96.36.19912", supplied by Advanced Micro Devices. Realtek properties, details, shows "Driver Version 188.8.131.5210", supplied by Realtek.
The motherboard is Intel DZ77BH-55K. The box has a Dolby logo, but Intel is no help. No one there will profess any knowledge of Dolby, much less how to repair my situation.
The OS is Windows 7 Professional, 64 bit.
The CPU is Intel i7-3770, 3.4G.

Maybe you have the wrong driver for your on-board audio, I'm seeing the latest version as
184.108.40.20604 for your specific motherboard.
Intel® Desktop Board DZ77BH-55K
Look for the update to your Realtek driver dated 1/14/2013 and download it.
Completely remove the current Realtek sound driver and software (if any) prior to installing the new, then restart computer.
You should also check for other newer drivers from the above link and store them in a safe place, and or bookmark the link.DRIVE IMAGING
