As far as Windows Services are concerned, some of them are set on Automatic, while some are Manual type. Some may even be set at Delayed. Windows Audio Service is set on Automatic. This means that, whenever you start your computer, Windows will start this service by itself. But what if Windows is not able to start this service automatically? The result is, no sound at all from your system. Now suppose, you open Services window by running services.msc command, and try to start this service. What if you receive the following error?
Windows could not start the Windows Audio service on Local Computer. Error 0x8000706: The endpoint is a duplicate.
Generally, such type of errors can be solved easily by executing SFC /SCANNOW command with an administrative Command Prompt. The reason behind this kind of error is many times due to the usage of third-party antivirus on the system. Usually, the antivirus program marks the file as a virus and puts them into the quarantined items list, and thus the associated services with these files get affected.

1. If the Audio Service is not running, go to another computer that is running the same edition as on the issued system. Also, both system should have the same architecture like 32-bit on both machines. On another computer, press Windows Key + R combination, type put regedit in Run dialog box, and hit Enter to open the Registry Editor.
2. In the left pane of Registry Editor, navigate here:
3. Now you’d be able to see this dialog. Save the registry entry at a USB drive so that you can easily move it to the affected computer.

Finally, reboot the machine and re-try to start the Windows Audio Service, you should now be able to do so without any problem.
