Windows 11, "no audio devices found" both input and output. What happened to the speakers in my laptop?

* Changed to a question

Hi, after windows 11 update I have problem with audio: no audio device is installed. Please help.

I had exactly same problem with my Lenovo Laptop.

In the service list, there was 1 service not starting: Intel(R) Audio Service.

Then, in devices manager, the corresponding device, Intel Smart Sound Technologie OED, had its driver not working.

I update the driver for this device and the problem was solved

I'm having the same problem. I just downloaded two new updates that might have something to do with this, but I have no idea what to do. I have attempted the sugggestions here and the auto-troubleshoot with no luck. Anybody got suggestions? Thanks in advance!

P.S. Here is some info:

-Updates

-Device info

I found your reply more helpful than the Microsoft agent. I also had an error under Intel High Definition DSP.

How can this problem be a hardware issue when the problem exists on Lenovo, Dell, HP, etc.

Very frustrating as it happened out of nowhere.

If your device model is UM5606WA, then install this V6.0.9694.1, if already tried means, share hardware device id of realtek audio chip
