Q & A: Windows can not start windows audio service?
Q: Hello, my computer has an audio service not running, and no sound, in the control layout --- management tools --- Service --- windows audio can not start this option, suggesting that windows can not start windows audio service (on the local computer) Error 1079: The account of this service is different from the account running other services on the same process.

A: It may be because C:\\Windows\\System32\\audiosrv.dll file was deleted by mistake
You download an audiosrv.dll file and put it in the System32 directory, then run it. Enter the command: regsvr32 audiosrv.dll. Will prompt: c:\\windows\\system32\\audiosrv.dll has been loaded, but the Dllregisterserver input point cannot be found and the file cannot be registered. Don't worry, there is still a step to do, enter the command: regedit Run to open the registry, find the key "[HKEY_LOCAL_MACHINE\\Software\\Microsoft\\WindowsNT\\CurrentVersion\\Svchost\ etsvcs]” Open netsvcs, double-click the default, in the data Enter "“AudioSrv”" in the value.
OK, you can now regain control of your sound card. Go to Service Management and open your Windows Audio service. Try a piece of music.
If the audiosrv.dll file is not deleted by mistake, it may be caused by a program related to the sound that you closed Windows. You can set as follows:
1, control panel - all control panel - management tools - services - windows audio right-click properties - general - startup type: automatic - start - apply - OK
If the above method does not work, you can set the following :
2, control panel - all control panel - management tools - services - windows audio right-click properties - login - this account - browse - enter the object name to be selected - local service - OK - enter your own common password - application - OK - Open windows audio again - General - Startup type: Auto - Start - Apply - OK
