Update KB5050009 and KB5043080

Anonymous

I'm chasing my tail here, is there some properly tested software in your library? I'm on a 7 month old Dell with i9, lots of RAM and latest 11. This is the second time sound has been a problem (last time I had to wipe the whole system to get sound back).

For some reason cumulative update KB5050009 won't install (that being after after 4 attempts to download it) - I am hoping that this solves the problem of no sound through the USB system (2 new Dell U2424H screens with speakers).

So, I went to the catalog.updates and downloaded it separately in case of file error - then found that I need the standalone installer KB5043080 to install 5050009 from outside the automated process. So I downloaded that file also. I'm pleased that access to them is straightforward.

The 5043080 (standalone installer) was slow to unwrap, and seemed to go through the install process (the green progress bar seems to work OK). But then I'm faced with "The following updates were not installed....KB50430380". So it did not work after all.

Ye gods. So I have the files, but 5043080 wont install, and I need that to install 5050009 - because that won't install on the standard auto-update methods.

Does anyone have any ideas?

Hi DLynch456,

I'm an Independent Advisor and I'm happy to help you.

Please try these steps:

Run Windows Update Troubleshooter

Open Settings (Win + I) > System > Troubleshoot > Other Troubleshooters
Run Windows Update Troubleshooter
Restart your PC and try installing KB5043080 first again.

Manually Reset Windows Update Components

Open Command Prompt (Admin) and run the following commands one by one: net stop wuauserv
net stop cryptsvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptsvc
net start bits
net start msiserver
Restart your PC and attempt the update again.

Since KB5043080 is required for KB5050009, force its installation using DISM (Deployment Image Servicing and Management Tool):

dism /online /add-package /packagepath:"C:\Path\To\KB5043080.msu"

*Note: Replace "C:\Path\To\KB5043080.msu" with the actual path of the downloaded file.

If the installation completes successfully, restart and try KB5050009.

If DISM fails, try repairing system files before another attempt:

Open Command Prompt (Admin). dism /online /cleanup-image /restorehealth
sfc /scannow
Restart and retry the updates.

Additional notes on sound issue

USB Audio Fix: If your sound issue persists after the update, check Device Manager (Win + X > Device Manager), uninstall and reinstall USB and sound drivers.
Dell U2424H Screens: Check if there’s a firmware update available for these monitors from Dell’s website.

Final steps

If none of these work, try installing KB5050009 using an in-place upgrade with the Windows 11 ISO from the Media Creation Tool.
If sound remains broken, rollback the last update affecting audio drivers (Settings > Update & Security > Recovery > Go back to the previous version).

Let me know which step worked or if you need further guidance. :)

Hi David,

That's great news! Maybe you need an additional HDMI audio driver for the external monitors.

Also, you should not be able to use laptop and screen audio simultaneously, did you check if you have more than one device to select when using the button next to audio bar when clicking the sound icon in your taskbar?

Looking forward for your response. :)

Answer 3

Hi, Thanks for your interest and comments.

I managed to get the updates all installed (thanks for your list) - it took an OS rebuild, but I left the system to do that overnight.

Still did not sort it out.

I contacted Dell and was advised to install "realtek-High-Definition-Audio-Driver_1CHWC_WIN_10.0.251.1.1_A05"

That cause a couple of restarts, and then the laptop audio was back - so at least there is some sound now.

Still no sound from the new Dell U2424H monitors.

I will wait and see if there will be a patch put out for this issue.

I appreciate your comments.

David

Hi DLynch456,

Media Creation Tool is an upgrade assistant used when upgrading or making a new Windows installation. An in-place upgrade will reinstall windows in a special way, by making an "upgrade" of the same version of windows on top or your current installation, without making any changes to your files and folders.

Personally, this way has resolved so many issues for me in the past, please consider doing it.

Here's a step by step guide on how to perform an in-place upgrade, works for Windows 10 and 11:

Please, let me know if this helps!

Answer 5

Hi Francisco: I have tried most of that, but with the following results:

The Update Troubleshooter Diagnostic failed to run. I find that bizarre.

The manual reset of components was not fully successful (esp. stop msiserver & renaming catroot failed)

Very odd.

Then tried to run auto updates just in case - but no good.

I think I will try the sound audio fix you suggest, next.

I have no idea what a Media Creation Tool is.

I will let you know if I get anywhere.
