How to fix failed to play test tone windows 10

A few days ago I updated the operating system of my computer. There is no output sound on the computer after the Windows update. I'm checking all the connections in my soundbox, And the connections are all right. I have done many methods to fix this problem. The last time I got a method, that fixes your Windows sound system.

Open any browser. Search by typing Windows 10 Sound Driver. The first row will show a download link, Realtek high definition audio driver. Click on this download link. This is Intel's official audio driver. Now download the audio driver. Now go to the download file. Now unzip the file. Install the audio driver. At the end of the installation, you need to restart your computer. This type of window will appear after restarting the computer. You need to restart your computer once again.
Hopefully, your problem will be solved after restart the computer 2 times.
