    No audio device in Windows 10


    A few months ago, I upgraded my from Windows 7 to Windows 10 without problems. However, my Asus X73E notebook sometimes completely froze, so I decided to reinstall Windows 10 from scratch. Now I get the message "no audio output device installed". The High Definition Audio-Controller driver from Microsoft shows the error 10 ("device could not be started").
    So I tried installing the Windows 10 audio driver from Realtek, but the installation gave me a bluescreen (System Thread Exception Not Handled RTkvhd64.sys). I tried installing a Realtek audio driver for Windows 7, but that driver doesn't start (message "the request is not supported"). If I boot from a live Ubuntu USB-Stick, the sound works without problems... What am I doing wrong?

    Try this.
    Go into Device Manager (right click Start Menu button, then click Device Manager) Open up the tree under Sound, video and game controllers. You should get something like this:

    There are only hidden items under that node. If I install the Windows 7 audio driver from Realtek, it appears there but with a "warning sign" (same as the High Definition Audio-Controller).No audio device in Windows 10-devices.png

    Try uninstalling the High-Definition Audio Controller, restart and see if that helps. You should do the same if you find the Realtek device in there.

    I unistalled it and restarted. It automatically added itself again but it still doesn't work. I managed to install the newest Realtek driver and added it as legacy hardware, but it has a "warning sign" next to it (even after uninstalling/restarting etc.). The error message says "the request is not supported".

    Have you tried removing the Realtek device from device manager and checked the box to delete its drivers?

    Don't reboot after that. Run the latest Realtek installer; it should install drivers without uninstalling the old ones and rebooting the machine.

    I don't know if that will help, but it may.
