    Audio devices disappear after failed update


    My computer i7-6700K, ASUS Z170-Deluxe, 16MB ram was working fine until it tried an update to KB50003637. During the update, it BSODed with a PAGE_FAULT_IN_NONPAGED_AREA error, after which it notified me that the update had failed and attempted to return to its previous state. However, when Windows restarted, I was getting a red X over the speaker icon on the taskbar, along with "No audio output device is installed" and "Speaker Setup UNKNOWN" messages when you hover or right-click on the icon, respectively. Running the Audio Troubleshooter only tells me they're sorry that they couldn'

    Audio Devices via DP/HDMI "disappearing" after 2004 update

    After updating to 2004, either my monitor or tv would disappear from the audio device list when:

    (monitor is on, I turn on tv, and turning tv back off.)

    It would only show either the monitor or tv on the audio devices list. Unplugging and plugging hdmi/dp cable would not work since it would only show the last connected device's audio.

    Downgrading GPU and GPU audio driver did not work, "workarounds" are either to reboot or disable and re-enabling Nvidia audio driver

    Unlocked Realtek HD Audio Drivers Windows 7 & 8 (With Dolby Digital Live and DTS Interactive)

    I originally followed the step on page 37. I used modified 2.75 dll and DTS/dolby shown in audio properties and working fine. After update to windows 10 build 15063. Realtek manager disappeared from system tray and DTS disappeared from audio properties, so I repeat the steps on pages 37.

    DTS is back in the audio properties, but when try to enable it, it says 'format not supported by this device.

    how to fix this?

    Audio devices disappear after failed update

    My audio output devices have disappeared from my HP laptop.

    I have an HP laptop running Windows 10. My audio output devices have disappeared. Not just no devices installed, but no devices listed in Device Manager. Tried troubleshooting and still no devices found. Tried connecting USB speakers, but those were not
    detected either.

    Suggestions?
