Hi, thanks for the help

i can not do your 6, it not give me no device to choice

when the troubleshooter is done the result is with a exclamation point  (in yellow triangle) "è possibile che non siano state rilevate modifiche hardware" that in english should be "it is possible that hardware changes have not been detected" or something near

Thank you for posting back.

 

I appreciate your efforts to try and resolve the issue.

 

As a workaround, request you open device manager by doing a right-click on the Windows button/menu. 
Expand “Sound, Video and Game controllers” or under “other devices” in Device manager

To find the audio drivers installed on your computer. 

Right-click on the audio drivers listed there and uninstall the Intel high definition audio and Realtek audio drivers listed there. 

Delete the drivers if prompted during the uninstall process.  

Once done, click on View and select Devices by connection on the Device manager.  

Expand ACPI x64 based PC. 

Expand PCI Express Root complex and right-click on Intel Smart Sound technology Audio controller and uninstall the device.  

Make sure to delete the driver if prompted during the uninstall process.  

Once done, click on Action and Scan for hardware changes twice in the device manager.  

Close device manager.  

Open Settings from the Windows menu. 

Click on Update and Security and check for updates to get the new audio driver for your computer.  

  

This should resolve the issue. 

Hope this helps! Keep me posted for further assistance.
