No sound after installing the latest Windows version 24 H2

[Artist1001]

Hello,

I recently downloaded and installed the latest Windows 11 24H2 version and now I don’t have sound. It appears that the sound driver is not compatible with this version of Windows.

I tried everything, including deleting and reinstalling the driver,  trying to find a different driver on HP’s support website, troubleshooting with windows troubleshooter or HP Support Assistant. Nothing worked. 
I chatted with Microsoft support for a couple of hours to no avail. 
I use the computer for work and can’t afford not having sound. I need it for meetings etc. 

I would appreciate any help. 

 The computer model is HP EliteOne 800 G5 23.8-inch All-in-One. The driver is HP Synaptics, version 8.65.317.104. Driver date: 7/5/21. 

Thank you. 

Seth.

Same here, but on ProDesk 400 G5/6 Systems.

Had to reverse to 23H2.

Dit you solved it?

No, I wasn’t able to solve it. I bought a sound bar. It’s not perfect but at least now I have sound.

You have to uninstall the update. That was the only way we could get sound. We also updated the drivers after we uninstalled the update.

Same issue but with HP ENVY Laptop 17m-ch0013dx

Uninstall the sound card (Synaptics HD audio) from Windows device manager using the Uninstall Device menu, then restart the computer. The sound problem will be solved.

Note: Apart from this method, it is not possible to find a solution by updating the driver.

After uninstalling the Device Manager > System devices > High Definition Audio Controller and restarting, still no sound. Then went to hp.com support > EliteDesk 800 G5 Desktop Mini PC > Software and drivers > Windows 11 23H2 (since no 24H2), downloaded the Driver-Audio > Synaptics HD Audio Driver (Version 8.65.319.200 Rev A, Release date Sep 25, 2024) file sp115227.exe. When downloading, it recommended using the Download and Install Assistant. But since HPIA indicated it did not have info for version 24H2 and HP Support Assist had not fixed the sound problem, I clicked on "No thanks, I will download and install manually". Executed sp115227.exe which put added the C:\SWSETUP:\sp115227 folder. In that folder, executed HPUP.exe but nothing seemed to happen. So opened folder src\driver\ and executed Setup64.exe which opened up an installation window. Ran the installation, it ended successfully, restarted the computer, and now have sound!

Hope this works for others. And hope HP releases Windows 11 Version 24H2 Sofware and drivers soon for all of their 24H2 compatible machines. And hope HP updates HPIA and HP Support Assistant to update any drivers needed for 24H2. I'm also putting the above info into any other HP Community entries I've seen about no sound after 24H2.

Very good instructions. Unfortunately it didn’t work for me.

Sorry to hear it didn't work for you. Guess I was lucky. We just need HP to release Windows 11 24H2 drivers for all of our models that can run Windows 11.
