    Stereo Mix missing after Windows 10 upgrade [Solved]


    I had a Dell Windows 7 computer and after upgrading to Windows 10, I don't have Stereo Mix under recording devices. Apparently I need a new driver because I have "Show Disabled/Disconnected Devices" checked.

    I checked Device Manager and it shows HD audio device.
    I displayed the properties and it shows the manufacturer as Microsoft.
    I then checked my Dell Service Tag recommended drivers and it shows I use a Conexant Smart Audio Driver, so I assume I have a Conexant audio device.

    I found the following driver on Softpedia and downloaded it to a USB device:
    Conexant SmartAudio HD Driver version 8.66.31.68 for Windows 10

    I used 7-Zip to extract the files and got a warning:
    "There are some data after the end of the payload data"

    Is there something wrong with the download because of the warning?
    I tried downloading it a 2nd time and got the same warning.

    I tried to install the driver via Device Manager.
    Right clicked on HD Audio Device.
    I selected Update Driver, Search this computer and selected the USB drive.
    I clicked Next and the driver failed to install with message "The best driver software for your device is already installed".

    I'm I doing something wrong?
    How do I verify I have a Conexant audio device and this is the correct driver?

    Thank You

    Edit:
    I failed to say Audio works perfectly except for the Stereo Mix problem.

    When I previously looked at my Dell account, the description for the Conexant Smart Audio Driver only included Windows 8.1, so I assumed it wasn't for Windows 10. I took a closer look and saw it was updated Dec 2015. At the bottom of the page there is a line "Supported Operating Systems". When clicked it expands to show it also supports Windows 10. I downloaded the driver and when double clicked, it automatically installs. I re-booted and now my Stereo Mix is back.
