HP EliteDesk 800 G9 machines - "No audio devices are installed"

[DaleFoster]

Having an audio problems with our HP EliteDesk 800 G9 machines. Our latest effort involved building a new CPU. Audio stops on newly deployed desktop after reboot

Getting "No audio devices are installed" under the Playack tab under Sound Settings. Under Trooubleshooting audio problems it says "No output devices found.
Seems to be uers wih speaker with "Headphone" jack having the issue.

- USB Audio seems to be fine.
- No sound drivers not present under device manager.
- Installed Driver - HP Elite Mini 800 G9 Desktop PC (didnt work)
- Tried https://www.driversupport.com/knowledge-article/exploring-realtek-hd-audio-drive-failures-and-common... (didnt Work)
- Tried rolling ack firmware to sp145985.exe 2.10 (didnt Work)

Same issue here with same machine Desk 800 G9.

I wound up removing all Realtek devices from the machine and uninstalled their drivers (in safe mode). Then installed the Realtek drivers from the HP website. This fixed it... until Windows then installed "updated drivers" through Windows Update. Went through it again... and turned off automatic driver updates from Windows update.

This worked fine for a few days... then it stopped working again. And I found Windows update had installed the drivers AGAIN despite my efforts to prevent this.

Seems to be when the following updates get installed by Windows update:

It's causing windows audio service to crash about 2 seconds after starting.

Further to this, I saw Dale Foster's other post about the same issue with notebooks and that webcam was suspected.

Unplugged my Logitech C920. Rebooted. Have sound.

Plugged it in. A few seconds later, Windows Audio Service crashed.

Sigh. 

[ThierryThierry]

We have the same problem. Not possible to get sound out of it. Tried different options without success.

Hey just chiming in we are having the same issue as well in our school environment

Happening to  HP Pro SFF 400 G9 Desktop PC on at least 2 devices ( Win 11)

Seems to be pointing to the realtek drivers installed recently

[FineAgro]

Has anyone found a solution yet? I have at least 3 users reporting all the same sound issue and messaged HP but still await a response or proposed fix. 

[dchc-andrew]

HP support sent us a powershell script to run to fix this issue. It only works on average, for the day. It's basically removing all of the HP OEM drivers. By the end of the day/overnight. Windows update is just downloading the drivers again and breaking it.

Any webcam connected to the computer? Disconnect it and see if something happens with the sound.

Today i found at my HP Elite Desk 800 G9 , after a month waiting and trying the solution
With a recent on-line tool , i got the recommendation to upgrade my Real Tek HD audio driver with the sp149591.exe from HP which is from 17.10.2023 recently. After this installation and a restart of my PC the audio  works well again directly!

Hopefully it can helps others too with this longterm issue already. Succes!

[Steven162]

Exactly the same issue here with an Elite Mini 800 G9. The only successful workaround is to uninstall onboard Realtek and driver in Device Manager. This will work for a day or two before the device is re-installed by the system and audio is once again broken.

I've tried all the fixed listed here - no joy. 

HP if you're listening - can we expect a resolution to this?
