Windows 10: How to force W10 in (re)install a driver from the MS repositiory for W

    How to force W10 in (re)install a driver from the MS repositiory for W


    I have a Toshiba laptop that has a Conexant audio subsystem. The sound system is misbehaving and I suspect a driver issue. Here is the problem: I was running windows 7 and upgraded via the free upgrade offer to Win 10. Everything worked OK for a while and then the problem with the audio system appeared. I checked the Toshiba website and they list no drivers for Win10. I cannot find enough specifics about the Conexant audio system on my laptop to get one from the Conexant website. (if they even have w10 drivers)

    My question is: how can I force Windows 10 to download and install a win10 compatible driver for the audio subsystem? Aside from going into the Device Manager and finding the device, how can I find out what driver MS is installing for the Conexant device?
    Thanks

    Hi, rt click properties, Driver in device manager should show the version, and Driver Details more.

    If you want to force a complete reinstall, then in device manager, when uninstalling the driver, tick the check box to also delete it. Then reboot.

    Downloading from the manufacturer's site carries the usual caveat of it not being fully compatible for laptops, but it has certainly helped me in a couple of instances.

    My Toshiba laptop has Conexant audio too. The initial free upgrade from Windows 7 to the first RTM Windows 10 (10240) installed MS-supplied Conexant smartaudio HD drivers which initially didn't work without a workaround (run msconfig.exe and under “Boot” – “Advanced Options…” limit your “Maximum memory” to 3072) - apparently a known bug that wasn't fixed in time for the RTM, though it was fixed later in one of the early CUs.

    Somewhere along the line, in upgrading to 1511 and now 1607, Windows 10 replaced my Conexant drivers with the generic Microsoft High Definition Audio device which works perfectly.

    This is what I want to do: force w10 update to install the generic MS HD audio driver. Given that there is no w10 driver by Conexant, and there doesn't seem to be any other correct driver to download, I want to force W10 to install the generic driver you mentioned. Unless someone can tell me where to download this generic driver, then I can manually install it myself. Thanks for your help.

    Which version of Windows 10 do you have? A download shouldn't be needed, HD Audio is supplied as part of Windows 10. There's an hdaudio.inf file in my C:\Windows\INF folder that has a creation date the same as all other files installed when I upgraded to 1607.

    Before trying anything, make a Restore Point!

    You should be able to manually install HD audio from Device Manager. Look under 'Sound video and games controllers'. You should be able to change the driver for the existing audio device there by clicking its 'update driver' button, selecting 'browse my computer for driver software' and browsing to C:\Windows\INF.

    Alternatively, uninstall the existing driver then use Device Manager > Action > Scan for hardware changes.

    Oh, OK, so it seems you are saying that when W10 was installed, it copied down a generic class HD audio driver, and that should be located in C:\Windows\INF.
    TYVM, will check it out!
