[German]If you own a business PC HP Prodesk 600 G4 with Windows 11 23H2, you could run into problems when upgrading to Windows 11 24H2. The sound from the Synaptics audio unit is missing after the upgrade because the driver provided by HP causes problems. However, blog reader Markus Grosche sent me a workaround by e-mail and in the discussion area, with which you can "get sound again" (thanks for that).

The HP Prodesk 600 G4
The HP Prodesk 600 G4 is a business PC, still offered as "refurbished" with various features by used equipment manufacturers. The device can be purchased with various Intel iCore CPUs, RAM, SSD and with Windows 10 Pro or even Windows 11.
German blog reader Markus Grosche writes that he owns an HP Prodesk 600 G4 with Core i5 8500. I deduce from various offers and this article that this business PC will be delivered with Windows 10 (Home or Pro) before or around 2020. Dealers will then upgrade it to Windows 11 when reselling it.
Synaptics audio issues in Windows 11 24H2
The blog reader wrote that the HP Prodesk models with Synaptics audio are widely available, as they are offered on the second-hand market by refurbished vendors for little money. But the model tends to cause audio problems.
After Markus Grosche updated his HP Prodesk 600 G4 (with Core i5 8500) from Windows 11 23H2 to Windows 11 24H2, the audio output was missing ("the sound was permanently gone").

HP currently only offers the driver 8.65.319.200 Rev. A on its product page as "current". According to Markus, the HP audio controls were already not working properly under Windows 11 23H2 (the service started with a delay of several minutes or not at all).
Driver from the Update Catalog
Markus Grosche then found various versions of the audio driver in the Microsoft Update Catalog. He opted for the latest Synaptics – MEDIA – 8.65.321.20 audio driver with a size of 116.7 MB. This is how to install:
- Download the cab file from the Update Catalog and unzip it into a directory using 7Zip/Nanazip.
- Then in the device manager click on Update Driver, then twice on the lower option and then on Disk and then specify the exact directory.
- Ignore the warning and install the driver.
Now everything is working again for the blog reader: the HP audio controls are working properly, look different now and are available in the tray bar. Thanks for the hint, maybe it will help.

This fixed the issue on my HP EliteDesk 705 G4 as well. Thank you very much for posting, much appreciated!
Thank you so much for your post!
I have just updated to 24H2 and had no sound at all in my HP Elitedesk 800 G4. I downloaded the file you linked but I could solve the problem without it, just in case anyone reaches this post with the same problem.
All I have just done is: Device Manager > Sound, video and game controllers > Synaptics HD Audio > Update driver > "Let me pick…"
I had two options, "High Definition Audio Device" and "Synaptics HD Audio", selected the first one, OK to the warning and that's it, sound is back!
