Lost all audio after May, 2021 Windows 10 update!!!!

This fixed my sound issue with 21h1, but the Ctrl Alt Del is still there (but I can live with that)

Thanx for this fix!!!

MicroSoft's recent Windows 10 updates have really caused more problems than I can see have been fixed. Is the B-team working Windows 10 now? Are they trying to drive people away to upgrade?

It's gonna drive me to Linux...

I would say it is likely their C-team! :)

Nikolay , acatually, CTRL-ALT-DEL fix is also described in this thread, launch secpool.msc , then Click Local Policies to edit an Audit Policy, a User Rights Assignment, or Security Options, find the relevant line and enable/disable.

I also followed your way with copying of Default key , and this worked ! Can anybody explain what actually happened ?

To open 'Windows Registry' in the command prompt, press and hold Windows key + R. In the 'Command Prompt', type regedit, then press Enter. The 'Registry Editor' will then pop up and you will want to click HKEY_LOCAL_MACHINE. Then SYSTEM. Then CurrentControlSet. Then Control. Then Terminal Server. Then WinStations. That is how you get to the actual 'Windows Registry' with the 'Binary Data' and 'Values.' Now, you are going to want to Export the Winstation .REG Folder by clicking File Export. Save to a safe place.

At this point you are safe to create your own separate .reg document. Right click on the desktop, click new, click text document. Make sure to edit the end of the document to .reg from .txt. Then copy and paste inside the .reg document you just created, which you can name 'Fix_Audio.'

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations]

"ConsoleSecurity"=hex:01,00,14,80,9c,00,00,00,a8,00,00,00,00,00,00,00,14,00,00,\
00,02,00,88,00,06,00,00,00,00,00,14,00,01,00,00,00,01,01,00,00,00,00,00,05,\

04,00,00,00,00,00,14,00,bf,03,0f,00,01,01,00,00,00,00,00,05,12,00,00,00,00,\

00,14,00,89,00,0f,00,01,01,00,00,00,00,00,05,13,00,00,00,00,00,14,00,81,00,\

00,00,01,01,00,00,00,00,00,05,14,00,00,00,00,00,18,00,bf,03,0f,00,01,02,00,\

00,00,00,00,05,20,00,00,00,20,02,00,00,00,00,18,00,21,01,00,00,01,02,00,00,\

00,00,00,05,20,00,00,00,2b,02,00,00,01,01,00,00,00,00,00,05,12,00,00,00,01,\

01,00,00,00,00,00,05,12,00,00,00

After saving, Execute the file by clicking on it and it will automatically update the Console Security .reg data inside the Registry Editor. You will see the number change beside the ConsoleSecurity. Restart your computer. Boom...shahckah lahckah! Your Sound should be back :)

Just want to say this worked for me and thank you very much to whoever the genius was that figured this out. The issue has been plaguing me for months and that ease of access workaround was driving me crazy.

To pay it forward, this registry edit originally did not work for me and I don't have much experience editing registries so I kept getting the error "Cannot import file: The specified file is not a registry script."

The problem was because when I copy and pasted, there was an extra space above "Windows Registry Editor Version 5.00" in the file. That needs to be removed for this fix to work.

Then the audio will continue to be disabled until you restart your computer. Once you done so, it should work normally and perfectly.

Hi GainbrainX -

Thank you for the quick response. Did System Restore works or not? If not, let's try to create a new user profile and check if the same issue will persist.

Create a new user profile

• We will try to create new user profile to check if the issue happens on all windows users on your computer or just isolated on the current profile that you're using.

1. Open the command prompt with elevated access (Administrator Access)
2. Type the below command and hit enter every after command.

net user "account name" /add

(change the "account name" to any name that you preferred)

net localgroup administrators "account name" /add

(change the "account name" with the name that you put in the first command)

3. Close the command prompt and switch to the new user.

Check if the same issue occurs on the new user profile. If in case the issue still persist on the new user profile, perform In-place Repair.

In-Place Repair

• In-place repair/upgrade or repair reinstall is a process of re-installing Windows without touching any of your applications or personal files. In this way if there's any data corruption, damaged system files or missing system files on your computer, this repair will fix or repair them.

To start we need to download an ISO file of Windows 10 and save it to your computer. Please follow the instruction on the link below to create an ISO file

https://support.microsoft.com/en-us/help/402819...

After the ISO is created, follow the instructions on the link below created by PaulSey, Microsoft Agent, on how to perform repair install on your computer.

https://answers.microsoft.com/en-us/windows/for...

This process will take some time to complete so you need to be very patient in waiting until the process completes. Once done , restart your computer and check if the issue is resolved.

Regads,

Thank you for responding. I would be happy if it were something simple. Something I've just overlooked as I have a habit of doing. Yes, I've done those things and many, many others. It's some information regarding the output format has been lost. between the audio output device and my soundcard. Every time I reboot, I get this RunDLL error saying there was a problem starting a module called PYTJDV~1.DLL, which I believe is a Python module. Says it can't find it. This appeared the same time I discovered the music died.

Hi,

It might seem like it's self-evident, but have you made sure your volume mixer is set up correctly. To open the volume mixer, right-click the volume icon in your taskbar and select volume mixer. Then make sure the audio output is not muted. You might have very well done this already but from ow own experience, I can tell that the problem can just be that simple.

Best of luck!
