    You mean the sweet pie with the orange "pumkin" is delicious. I don't think a pie with the green little zucchini would be that delicious. Before my system lost access to any audio/video device I used my SSD to capture 1080p60 video from the HDMI to USB adapter. I know I shouldn't put too much stress on the SSD, but I wanted to minimize access times to avoid any dropped frames. My system can capture 1080p at 60Hz and 8-bit per channel (24-bit total) color just fine on the SSD. I wouldn't risk using a mechanical disk. The adapter also supports 12-bit per channel (wide color gamut) capture, but my USB 2.0 ports (or another component in my system) are too slow and the video stutters, so until I upgrade it I can do only 8-bit per channel. The only compression I can choose is MJPEG that produces huge files, hence the huge data to backup. I convert the video to x264vfw after editing.

    People from Epirus, Thessaly, Cyclades and not only, does not share the same opinion and they always prove it.
    As for me, I know about video as much as a zucchini knows...

    Zucchini are best fried with tzatziki for side. You are welcome to visit Greece and see what I mean...

    Meanwhile I backup everything (I hope), so unless some miracle happens during weekend, Monday I will restore my system from the old SSD, fingers crossed...

    I believe that a simple in-place repair upgrade will fix it. It can be done from distance.

    I realized you live here in Greece. I was inviting other posters to come here for vacations.

    As for the in-place upgrade, already tried that but whatever incorrect entries did the malware in Registry propagated and the problem persists. I now attempt to return back to v20H2, fortunately I had kept the data. This could do the trick, otherwise Monday I'll restore the backup from my old SSD.

    Thank you all for your help.

    Hi!
    I also have this issue now, this happened after the 06-2021 cumulative update to 20H2 (the original 20H2 was fine).
    Pre-history:
    Actually, I couldn't boot correctly with 06-2021. It would show my desktop, with icons, but none of my auto startup applications launched, and either WDM or Explorer (or both) were hanging.
    Mousing over the Task Bar displayed the waiting cursor, and any number of things, including clicking the task bar, resulted in a dark gray screen (my color scheme), which would then not react to anything. I could still move the mouse.
    I could not bring up Task Manager or Process Hacker (not from the CTRL-ALT-ESC screen, not from the task bar (as that would trigger the gray screen)), launch an explorer window or RUN prompt (WIN-R).

    So I chose "Uninstall last quality update" from the recovery options. This seemed to work at first, but after restarting again (Windows seemed to still need to complete the configurations), the sound was gone.

    Same symptoms.
    • Audio devices and Sound devices show up in Device Manager
      • All devices report that they're "working properly"

    • But Windows says it can't find any audio output devices in various places (volume icon, modern "sound" settings)
    • The outputs (or inputs, for that matter) don't show up in the Playback/Recording tabs in the CPL window
    • DxDiag tells me "No sound card was found"


    I can confirm that this is a software issue:
    I restored a disk image I made before updating to 20H2 and the sound was working fine.

    I'm still very interested in getting this to work without having to use the month old image, though.

    I've tried:
    • Deactivating/reactivating sound devices in Device Manager
    • Using the troubleshooter for sound problems
    • Uninstalling and removing drivers in Device Manager
    • Installing generic drivers in in Device Manager, trying to update in Device Manager/windows Update
    • Manually adding a generic sound device/drivers in Device Manager
    • Manually installing the original drivers from the manufacturer's site
    • Displaying hidden items in Device Manager (in case any critical components were disabled and hidden somehow)
    • Changing the "UpperFilters" key in Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96c-e325-11ce-bfc1-08002be10318} to an empty string from "ksthunk"
    • Checking system integrity/auto repairing with SFC /SCANNOW
    • Checking system integrity/auto repairing with DISM /Online /Cleanup-Image /RestoreHealth
    • Plugging in USB soundcards
    • Making sure that the Windows Audio service (and Windows Audio Endpoint Builder) are enabled and running

    And probably some other things I can't think of at the moment, will add as I think of them.

    FWIW, the integrated sound card in question is a Realtek High Definition Audio chipset reporting as
    HDAUDIO\FUNC_01&VEN_10EC&DEV_0900&SUBSYS_1462D693&REV_1000
    But I doubt that that has very much to do with it, as the generic external USB soundcard and the NVIDIA HD Audio device also don't show up outside of Device Manager.

    If anybody has any more ideas, let us know!
    Thank you all for your time and help! :)

    So all of us that have an old model of Realtek HD audio card should avoid the optional upgrade after v21H1. If anyone from Microsoft is reading this, please make sure you fix this bug before turning the optional upgrade to regular.

    As said in my previous post, I tried to get back to v20H2. Somewhere the process was interrupted and now Windows 10 won't load at all! Yet another case of Murphy's law "if anything can go wrong, it will". So all I must do now is restore my backup from the old SSD.

    Thank you all for your help.

    Hello! It was done as said, I restored my system from my old SSD (cloned back the old SSD to the new SSD) and now it is up and running again, in Windows 10 Pro v2004 64-bit. I will carefully upgrade it again to v21H1, avoiding the optional upgrade that screwed it in the first place. Good job I had backup all my data before attempting to return to v20H2 without success! Take it as a general rule, always have a backup, even an old one saves your life, and always backup your data before trying something uncertain.

    I will mark the thread solved, although I would like to know a better solution than restoring from backup or resetting/reinstalling Windows. If anyone knows anything, please post.

    I don't know, "make sure you don't run into the problem in the first place", aka "go back in time and make a backup" doesn't really strike me as a viable solution.
    The problem wasn't solved, It's simply "going back in time" to a point before the problem existed :/
    A work-around suitable for many, sure, but the actual issue was neither figured out nor solved
