Yesterday the sound on my HP Omen computer stopped working for no apparent reason.  I found the video below, which fixed the problem:

The video is short, easy to follow, and doesn’t need the sound working to understand it!

The procedure on my machine was pretty much as shown in the video except:

1. The Device Manager was not listed when I clicked on the Windows Icon. Just start typing “Device Manager” and it appears.
2. The Sound driver listed for my machine was “Realtek(R) Audio”
3. I had to restart the computer after re-installing the driver.
