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

    Due to my frustration I deleted my AVG 2014 (Free), now I can't find that quarantined file. Tried restore point option in windows but my AVG2014 is all messed up, it doesn't open anymore. Regedit thing didn't work either. Wanted to reformat my windows 8.1 unfortunately the product key from Asus OEM single language is not accepted, this is really frustrating, but guess what if I run it with my usb linux boot, the sound is perfectly ok. But I need to use windows for some software of mine that can only work with it. Help please...
