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

    Sounds like the same things that happened to me.  It was due to AVG and I went directly to their support team and they took over my computer and fixed the problem.  Basically I watched and they restored a file that was isolated in the virus vault, just like explained in earlier threads on this site. Good luck.

    I tried everything I possibly could, and in the end I resorted to resetting my PC. Which worked at the cost of wiping my hard drive completely. But I backed up all of my files before then. Since I have a custom built PC I had to reset it by booting up my old Windows 8 installation disc and continuing from then on. Once I had re installed Windows 8 I later updated my computer back to Windows 8.1
