Hello DavidPK
Thank you very much for the help.
All perfectly.
After updating BIOS to F.18 version and updating the chipset driver, Intel SST Audio Device (WDM) appeared.
Two unknown devices are now speakers and a microphone. That's what these were unknown devices!!!
Now also the proprietary function Beng & Olufsen Play.

Once again - many thanks for the help!! 🙂

Hello DavidPK, I read your posts with interest at 2.00am this morning, as I had exactly the same problem, with an HP X2 10-n103na, running windows 10, version 1809, build 17763.316 (my daughter's ex laptop, who tells me the audio hasn't worked for a short while).

The laptop was saying no audio output device is installed. The Conextant I2S audio codec was installed, and there was one unknown device with hardware id as:

ACPI\VEN_8086&DEV_22A8
ACPI\808622A8
*808622A8

I re-installed windows as a clean copy,  updated the BIOS (or so I thought), updated drivers etc.

No joy, so was going to post a question to you, and thought I would double check what the BIOS was.  For some reason, it hadn't updated, and was still at F.00.  I have now updated the BIOS (is now F.18, the latest), and magically, I checked for drivers on the unknown device, it foudn them, and it turned into the Intel SST audio device, with sound now working properly!

Just wanted to post to say thank you, and also, in case others were still hvaing the same problem.

Many thanks, it was very much appreciated. HS
