Windows Audio cant be started, error 1740 (0x800706cc: Endpoint is a duplicate)

Hello. I need help. I lost my audio a few days ago, and it seems weird. How did it happen? I noticed it when I experience a control panel issue. When I open it, it won't load up and it cant be closed. The volume button on the taskbar says "The Audio Service is not running." I watched a video on how to solve it. I noticed, the Multimedia Class Scheduler is not running. I started it successfully. So now I started the Windows Audio service, but a dialogue box shows up and says what is on the attachment. Hoping for your reply.

If your AVG virus vault is empty and you get the error message of “Endpoint is a duplicate" try the following steps:

Open Regedit.
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AudioEndpointBuilder\Parameters.
In the right pane check the value of ServiceDll. If the value is %SystemRoot%\System32\Audiosrv.dll, it's the cause of the problem. It should be: %SystemRoot%\System32\AudioEndpointBuilder.dll.
Change the ServiceDll to it’s correct value.
Reboot your computer.

I hope this will help.
