Cannot find any play sound after updating window

[BaoLinhHa]

Hi everybody, 

I need help. My problem is:

- After updating window (I am using Win 11), I can not find any audio device (picture below):

- I tried to uninstall and re-install, but it does not work. 

- I tried to run Troubleshoot in Windows, but it could not find any problem 

- When I tried to use System Sound and re-connect with my Bluetooth speaker devices, I could not find any device to pair.

Now I need to figure out how to fix it to watch my movie. 

Please share with me the solution to fix this problem. 

Thanks and best regards!

Check for Windows Update and see if there is any new update?
Open start and search for feedback and open the Feedback Hub app and report this issue.
Try visit your device's manufacturer website and download and install the latest sound driver.

Yes sir,

I uninstall all the updates of Windows. But the problem still appears. :(

So confused.

Have you tried updating the driver as I mentioned earlier?
Try performing Clean Boot and see if the problem persists?
Have a look at:

Yes, you're right, we should update driver of the computer.
After updating driver, I can use the sound normally.
