I checked the software settings.  The output was selected for the correct output device  "Realtek". 1a. I was concerned about the Realtek driver as being the problem.  I was going to investigate it to see if I needed an even earlier version. 1b. I only used System Restore one time,  however, I ended up letting it run all night.  I figured it was going to crash my system, but it didn't.  The Welcome Screen was displayed when I came back to it in the morning. At any rate, I have solved the problem. In my searching, I discovered that there are other "troubleshooters" available in Windows 10.  If you don't have problems that often, you don't find answers. [IMAGE] I went to Updates > Troubleshoot > Additional Troubleshooters > Playing Audio.  Ran the Troubleshooter and it fixed my speaker problem.  I was amazed, I haven't had much luck with Windows Troubleshooters. I don't know what the troubleshooter did, but in checking all other locations for tests, the speakers work.  YEA!. Thanks for your help. Jerry
After getting 3 problems solved with my 8930, see: XPS-8930-what-does-EP-EXCEPTION-SUB-HEADER  I just noticed today that my external speakers (or any other speakers) stopped working.  This is after three days of solving the problems referenced in the thread above. Apparently someone else had a similar problem back in Mar 2021 and there was no solution. External-speakers-not-working  When clicking on one of the speakers the display shows little waves to represent sound.  I get the waves on both speakers but they don't work (no sound from any of the speakers). When I unplug my speakers from the back of my computer, I get a buzzing feedback noise in all my speakers, which indicates that they still function. Any help will be greatly appreciated. Jerry Here is a screen capture of my speaker test. [IMAGE]
