    @swarfega,

    I added a Softpedia link for 6.0.1.8040 to the first post to help.

    I did unzip the cab file from MUC and no success in getting it to install. I did the same with file on softpedia website and no success either. I believe that there something wrong with the cab files for 8037 and 8040 versions.

    I just installed 8040 from downloaded .cab file, no problems.

    I'm on Windows 10 Ent 64bit, ALC889 codec. I've just updated my driver to 6.0.1.8040 using the microsoft .cab.

    However after rebooting it was always asking me at startup the authorization to run RAVCpl64.exe (which is realtek control panel right?).

    I had to untick "always ask before opening this file". Is this normal?

    If Windows say you have the best driver already, then probably the new driver is not 100% compatible with your hardware (the hardware IDs in the INF file don't match your hardware). You can try to manually force-install it from Device Manager, but it might not work properly. Since all you have is a CAB file, you must extract the contents to a folder using WinRAR or other archiver. Then go to Device Manager, right-click on the Realtek HD Audio device, select Update driver software. Then select the last option and then again the last option. You should see a list of drivers and a "Have Disk" button. Click on that button and browse to the folder where you extracted the CAB file. Select the first device from the list and proceed. If it doesn't work properly, repeat the procedure and this time select the second device, next select the third and so on. If the driver is compatible with your hardware usually the first device in the list works and you don't have to try anything else.

    PS: I just downloaded the driver from WUC and manually installed it. I cannot judge the audio quality since my primary audio card is a Creative Audigy and I wouldn't like to connect speakers to the Realtek just for the test. Anyway, I spotted two Dolby Digital Plus installers, DolbyDigitalPlusAA.msi and DolbyDigitalPlusHT.msi. Both of them don't install and stop with an error message that Dolby Digital Plus should be installed. I realize this is only for certain notebooks that have some Dolby Digital hardware present, or am I wrong? Can I do some cheating in software (eg Registry) and install Dolby Digital Plus in my non-compliant PC? Would there be any benefit in the quality of sound or otherwise?


    Any info appreciated, thank you in advance!

    PS2: I had some typing difficulties while replying in this post. I had to press some keys twice or more to appear just once! My keyboard works ok in other posts or elsewhere. Do you have any idea why? Could this be an autocorrect or other bug?

    IMHO If manually trying to update the driver, it's simpler to
    • Select the first option Browse for driver software on your computer
    • Browse to the folder containing the driver files just extraced
    • Include sub-folders should already be checked (by default)
    • Click Next

    Windows will search all the INF files for you and select the best match. No need to guess

    This should work if the INF file contains hardware IDs that match your hardware. By going to the manual selection you can force-install even partial compatible drivers (not exact ID match).

    IMHO That's incorrect. It might appear that way but, behind the scene, it's the device vendor that determines acceptable matching IDs for a driver. I'll explain.

    Every device has one or more hardware IDs. It also has Compatible IDs. These IDs are burned into the firmware by the vendor when the device was built. By definition, the first h/w ID in the list is its "Device ID". Many spec analysis programs may only show the Device ID as the h/w id. They may not display the full list ids.

    When Windows searches for suitable INF matches it uses the full list of both Hardware IDs and Compatible IDs for the device. If any of the IDs defined within an INF match any h/w or compatible ID, the INF becomes (what i'll call) a driver candidate. When done searching INFs if Windows found more then one candidate, it evaluates and ranks each candidate. It uses driver "rank" to select the one it thinks the best match.

    So, partial matching isn't a function of how you update the driver but rather
    • The list of IDs burned into a device by the vendor plus
    • The IDs defined in an INF (as determined by the driver developer to indicate what IDs the driver supports)


    As an example, find below the h/w and compatible ids I found for the Realtek chip on a PC. (Use Device Manager to see them. Right click->Properties tab. Select Hardware ids then Compatible ids from the pull down menu). Windows would accept an INF that matches any of these. So, bottom line, it's the vendor that defines the IDs and partial matches that are acceptable

    /* EDIT */
    Note: For Windows to ultimately accept an INF also requires compatible architectures and OS. I refer to INF acceptance or matching by ID only just for easier reading
