Hi, i just recently got my convertible laptop. I have found ou that the audio doesn't work due to there being no audio output device installed, and after researching, I found out that there was a problem with the the Intel SST Audio Device. The device status stated:
"The drivers for this device are not installed. (Code 28)
There are no compatible drivers for this device.
To find a driver for this device, click Update Driver."
I tried updating the driver but the computer could not find any drivers for the device.
Can anybody fix this for me please?

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community!
I came across your post about the Notebook, and wanted to assist you! I have looked into your issue about your HP Pavilion x2 Notebook and issues with sound drivers not installed correctly. In the Device Manager, right-click on Double-click on Sound, video, and game controllers and select all that are listed and uninstall the Driver Software. Here is the download to the Realtek High-Definition (HD) Audio Driversp69248.exe.
You could try using the Windows Update Troubleshooting tool to fix any updates that have not come through for Windows. Please restart the Notebook twice to make sure all update have been completed!
You could also try in the Device Manager, click the arrow next to Display Adaptors to expand that category
Right-click on Graphics and select Update Driver Software if more than 1 Graphics adapter do 1 at a time.
Choose the option to Search Automatically for Updated Driver Software.
The Notebook should find and automatically install the updated driver
After the installation is complete, restart your Notebook.
Please let me know how this goes.

Hi, Same problem, I tried this. Uninstall driver OK. downloaded file OK. Ran. Exception 0xc0000409 and stopped. Then STT audio only shows as "unknown device". I seem to be going backwards!
Incidentally, indicator led on f6 key lights fromt time to time for no reason, (key does not switch adio on / off)
any ideas please?

I've had this HP Pavilion X2 for about a month and everything has been fine until today.
I now have exactly the same problem. Little red 'x' next to the sound icon. No audio output device is installed. I also have the same issues with the Intel SST Audio Device (WDM) in device manager.
Can't update the driver, since device manager can't find one.
Surely HP must have a version of this driver, they installed it in the first place. But if they have, I can't find it.
I've also noticed this issue mentioned on other forums, so we are not alone.
Come on HP. What is the solution?

Hi Fotodemon , and others..
Not a HP , speaking only in my name. This could be a solution.
Press Win+X key , or right click on Start button.
Open device manager.
Usualy , it must show „unknown device“.
Right click , choose „update driver“
Choose second (bottom ) option , let me pickup driver from PC
Again choose bottom option , pickup the driver from the list.
Choose audio controler
On the list – left side – choose Intel corporation (the first one !!! )
On the right side choose Intel SST Audio Device , and instal it.
You will be prompt not to do it , but do it hovewer.
It should solve emediatly the issue.
All the best!!!

Hi Faroo ,
Thry plese , what Fotodemon did first , instal chipsett driver from HP Support page , reboot.
If you still can see Intel driver , and it have no audio devices instaled , then deinstal the driver , reboot, it must show unknown device (properties , details , hardware ID , dev must be 8086 , which is code for Intel.
Then perform the troubleshooting from first post.
All the best ,
