    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", supplied by Advanced Micro Devices. Realtek properties, details, shows "Driver Version", 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 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.
    Invest a little time and energy in a well thought out BACKUP regimen and you will have minimal down time, and headache.

    Build your own system; get everything you want and nothing you don't.
    Latest Build:
    ASUS X99 Deluxe, Core i7-5960X, Corsair Hydro H100i, Plextor M6e 256GB M.2 SSD, Corsair DOMINATOR Platinum 32GB DDR4@2666, W8.1 64 bit,
    EVGA GTX980, Seasonic PLATINUM-1000W PSU, MountainMods U2-UFO Case, and 7 other internal drives.
