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

Question

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

Hi Marco,

The issue could be due to The Audio Service corrupted.

I would suggest you Try to copy and merge the audio service from a different Windows 8.

Note: Make sure the other computer is also a same as what you are using (Ex: If you are using 32 bit system then copy from 32 bit system only)

a. Right click on the start screen and select Run.

b. Click on Regedit.

c. Navigate to HKLM/system/current controlset/services/audiosrv click on audiosrv and then on the file menu select export and save the file on a thumb drive or disc.

Then copy that on your machine and merge it. Then restart your system.

Note: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Hi Vijay. Thanks for your reply. Can I use audiosrv of a Windows 7? Because I have another computer, but it's running on Win7 32-bit. Is it okay?
