Default Behavior

Windows Audio is a Win32 service. In Windows 8 it is starting automatically during the operating system startup. Then the Windows Audio service runs as NT AUTHORITY\LocalService in a process of svchost.exe, sharing it with other services. If Windows Audio fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the Audiosrv service hasn't been started.

Dependencies

Windows Audio can't start, if any service from the list below is disabled or not available:

Restore Default Startup Configuration for Windows Audio

Before you begin doing this, make sure that all the services on which Windows Audio depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

sc config Audiosrv start= auto
sc start Audiosrv

3. Close the command window and restart the computer.

The Audiosrv service is using the Audiosrv.dll file that is located in the %WinDir%\System32 folder. If the file is corrupted or deleted, you can put it back in there.
