If audio isn't working on your Windows 10 and you get "Windows could not start the Windows Audio service on Local Computer" warning, here is how to fix it.

Previously, we shared you the fix regarding the problem of audio not working after upgrading to Windows 10 which is covered under this link:

FIX : Audio Not Working After Upgrading To Windows 10

Today, in this article, we’re going to discuss yet another issue related to audio on Windows 10. Actually, few days back we faced a strange problem where we don’t have any output sound from the device. We checked the sound drivers and they were working fine. Also this was a dual boot installation, so when we booted to parallel operating system (Windows 8.1 in this case) installed on same device, audio was working fine. The issue was happening only with Windows 10. We then checked Windows Audio service in Services snap-in and the services was not running. Upon starting this service, this warning or error appeared:

Windows could not start the Windows Audio service on Local Computer.

Error 1740: The endpoint is a duplicate.

Since this is purely a service related issue, you should run SFC /SCANNOW command in administrative Command Prompt to fix it initially. The System File Checker should fix, if there exists any corrupted file related to audio service. In case, if you still have the same issue, you can try out these fixes and see if they helps you:

FIX : Windows Could Not Start The Windows Audio Service On Local Computer In Windows 10

FIX 1 – Using Registry Editor

Registry Disclaimer: The further steps will involve registry manipulation. Making mistakes while manipulating registry could affect your system adversely. So be careful while editing registry entries and create a System Restore point first.

1. Press W8K + R and put regedit in Run dialog box to open Registry Editor (if you’re not familiar with Registry Editor, then click here). Click OK.

Windows 10 Registry Editor

2. In the left pane of Registry Editor, navigate to following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AudioEndpointBuilder\Parameters

3. Highlight Parameters key and in the right pane of it, look for the Data against ServiceDll expandable registry string (REG_EXPAND_SZ). Since you’re facing this issue, the Data corresponding here should be %SystemRoot%\System32\Audiosrv.dll. Double click on the the string to modify its Value data.

4. In the Edit String box, set the Value data to %SystemRoot%\System32\AudioEndpointBuilder.dll and click OK. Close the Registry Editor window and reboot the machine. After a restart, problem should no longer persist.

FIX 2 – By Merging Audiosrv Registry From Another Machine

We have observed that this issue can also be resolved by merging the Audiosrv registry configuration from another machine on which audio is working fine. For this, you have export Audiosrv registry key (located at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Audiosrv) into a registry file with .reg extension. Please note that the system from which you’re exporting .reg file should have same architecture and equivalent or higher operating system edition as compared to issued/target/original machine. Fox example, here I am providing Audiosrv registry file from Windows 10, 32-bit edition. So if you’re having issue on equivalent OS or on 32-bit of Windows 7/8/8.1, you can merge this registry file to solve the issue:

Download Audiosrv registry file

Hope this helps!
