No audio from speakers; Failed to play test tone.


I have a Dell Latitude E6520 running Windows 10 Pro x64. When I try to watch YouTube I get no audio. Spotify plays and gives no errors but doesn't have sound. When I plug in headphone sound plays but as communications headphones. When I try to play a test sound through Speakers/Headphones I get an error that says "Failed to play test tone." When I try to troubleshoot it can't identify the problem. I have attached the report from troubleshooting.
Thanks in advance for helping.

Failed to play test tone (Sound stopped working) - The fix that worked for me.

This is actually submitted as a possible fix to the very frustrating issue of suddenly losing your sound.

This loss of sound might be due to a Windows update....

This is my story:

• Roughly 12-14Sep18 - Audio stopped while looking @ YT vids.
• All vols are fully up.
• There was a message saying if video (I think) doesn’t start, restart device.
• The on-screen Volume level METER still adjusted OK with laptop keys – but no sound.

NB: I later found that sound works OK when running in Ubuntu instead of Windows – proving my hardware to be OK.

• In Realtek HD Manager, testing sound was ineffective (the ‘TEST’ button greys when clicked, but nothing more happens – speakers should highlight when a test signal is received & played).
• In Sound Control Panel, Speakers/Properties/TEST speakers generates an error message
  
  "Failed to play test tone".
• In Sound Control Panel, no signal is registered from mic.

What I did (NONE of the usual standard replies had any effect on this issue).

1. Troubleshooting gave something like “Cannot access sound device…”
   
   – & “Not fixed”.
2. Restarted the Service - Windows Audio - no effect
3. Restarted the Service - Windows Audio Endpoint Builder - no effect
4. Uninstalled Realtek HD Audio (also ticking box to delete existing driver), then Re-started so that Windows would auto-re-install - no effect
5. Disabled all Enhancements - no effect
6. Used sfc /scannow - no issues found.
7. One suggestion related to settings in
   
   Computer Management/System Tools/Local Users & Groups/Groups
   
   – but Local users & Groups no longer exists in System Tools…. So this option no longer exists.

• Another suggestion I found was to restore the computer to a point prior to the sound failure.
  
  I PERFORMED THIS LAST OPTION AND MY SOUND WAS RESTORED.

This was such a frustrating issue – I hope the above info helps someone.

My restore point was also prior to some Windows updates, so when these are reinstated I might find that my sound fails again - but now I hope to be in a position for a quicker resolution.
