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:

  1. Open Regedit.
  2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AudioEndpointBuilder\Parameters.
  3. 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.
  4. Change the ServiceDll to it’s correct value.
  5. Reboot your computer.

I hope this will help.

Okay so i had this problem also and here is what was up with mine. My antivirus marked it as a virus and quarantined it withouit my knowledge so all i did was go to my archives or whatever it is called (im using AVG 2014) and restored it and my sound started working again. also when it says file already exists do you want to replace it REPLACE IT. So that's what i did and now my sound works, hope this helps

    Sorry for replying late i didn't realize i got replies, but anyway when you open up the avg desktop app thing just go to options and there should be a option called virus vault and i just looked at where the files are located and it was in system32 (i don't know why approved the quarantine in the first place, just not thinking i guess. shoulda saw where it was before) but anyway then just click on it and restore it then restart your computer and it should be fixed then. Good luck people!!! @Dom1989@Ranger401 @Seaferry hope this helped

    Having the same problem (I am also with AVG 2014). I have had a look in my virus vault but cannot see anything to do with Windows Audio being marked as a virus. Am I looking in the right place? Could you list step by step how you resolved your issue? Thank you.
