• Click on hardware and sound option. • Then click on “hardware and devices “and follow the on screen instructions. Method 2: I suggest you to follow the below article “No sound in Windows” and check if it helps. Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist. Thanks for your response. As mentioned previously, I did run Troubleshooter and it did not find anything it could correct.
I just now ran it again with the same outcome. I also did the checks to make sure that the speakers weren't being muted or the volume reduced by a hardware switch. They do not appear to be. The system appears and behaves as if it had working speakers - except it doesn't produce any sound. I suspect that the reason sound worked on this system under Win 8.1 was because there was a 3rd party sound driver on board from earlier versions of Windows. I don't know which one and cannot go back and check. Windows 10 doesn't identify the sound component, but the original driver Dell provided for this system was for Sigmatel STAC 92xx C-Major High Definition Audio.
