No sound - windows audio and audio end point builder not running/installed

I have the same issue, and applied your suggestion to check he running services.

Windows Audio runs well.

But Windows Audio Endpoint Builder is not existing in the list of services.

How Windows Audio EndPoint Builder service can be installed?

Thank you !

 

Windows Audio and Windows Audio endpoint Builder stop after Lock or Sleep

Hi Larry,

This issue may occur if the service is started by the Local System account instead of by the Local Service account (NT AUTHORITY\LocalService). The
Local System account may have insufficient permissions to start the service. For the
Windows Audio and Windows Audio Endpoint Builder services, follow the steps below:

• Set the service and any dependent services to run under the NT AUTHORITY\LocalService account.
• Click Start, type "Services.msc” in the
  Search programs and files box, and then press ENTER.
• Locate and double click the Windows Audio service.
• Click the Log On tab.
• In the This account text box, type “NT AUTHORITY\LocalService”.
  
• Set both Password fields blank.
• Click Apply and then OK.
• Repeat these steps for the Windows Audio Endpoint Builder service.
• Restart both services.

Let us know how it turns out.

 

Windows Audio and Windows Audio Endpoint Builder Services

• Additional memory cards were installed over Memorial Day weekend 2019.
• Audio Icon on taskbar shows red circle with X
• Speakers work.
• Rt Click on Start; Device Manager; sound card; Driver Tab; Update Driver.
• Audio Icon still shows red circle with X.
• Left click Audio Icon; go thru the trouble shooting instructions; "Both Windows Audio and Windows Audio End Point Builder services must be running for Audio to work correctly. At least one of these services isn't running."
• Select DETECTION DETAILS.
• Audio Endpoint: Render.
• Installed Audio Devices: This file contains the details stored in the registry for all installed audio devices. Registry log.txt.
• Then it wants me to do something with Explorer, but I use Edge.

Thanks for whatever help you can give.
