Steps to Re-enable Windows Audio Service
My friend called me yesterday as he was facing the problem of Audio not working on his computer. On being asked he told that by mistake he disabled all the services of the computer (Quite stupid, I know). But he was having a hard time to solve that problem as the services were not starting again and gave an error message each time.
Disabling the service included disabling the Windows Audio Service that resulted in audio of the system not working. Nor installing the audio drivers again solved the problem, neither restoring the system to an earlier time.
So if you also want to re-enable the Windows Audio service then try this fix:
1. Windows Audio Service is dependent on the Plug and Play service of the computer and you will see that disabling the Windows Audio Service also disabled the Plug and Play service.
2. So the solution is quite simple and is to just enable the Plug and Play service before the Windows Audio Service.
3. Type services.msc in the Run box to open the Services running in the system.
4. Enable the “Plug and Play” service before any other.
5. Now start the “Windows Audio Service” which will start without any errors this time.
You may require rebooting, but the sound has been enabled for sure.

This solution didn’t work for me. Plug and Play is started, but it still won’t let me start Windows Audio
The error I get is “The dependency service or group failed to start”. I guess it’s dependent on something else too but I don’t know what.

Okay, I got it. I snooped around through the services and found that Windows Audio service has the following dependencies. These services MUST be started first so that Windows Audio will start:
Plug and Play service must be started BEFORE
Windows Audio Endpoint Builder
BOTH of above must be started BEFORE Windows Audio Service
DCOM Service Process Launcher must be started BEFORE
Remote Procedure Call (RPC)
BOTH of above must be started BEFORE Windows Audio Service
Multimedia Class Scheduler must be started BEFORE Windows Audio Service
If you are having the same frustrating horrible Vista experience I was having, I hope this will fix the problem for you.
How to find this information:
1. Start > Run > type “services.msc”
2. Scroll down until you find Windows Audio
3. Double-click on Windows Audio
4. Click on the Dependencies tab.
5. See “This service depends on the following service components:”
6. If any component has a + sign next to it, click on the + sign to see which services are further dependencies.
7. Now, write down each service name and start them all… you must start the lower-level service so that the one above it (depending on it) will start.
How to start a service:
1. Run services.msc if it’s not already running
2. Scroll to the service you need.
3. Double click on the service.
4. On the General tab, see “Startup type:” and select Automatic.
5. Click Apply
6. Click the Start button
I really helps. This stuff can be really frustrating for non techie people like me!

Thanks Deefer.
1. Just enabling PlugandPlay did not work for me either as I had the same error message: “The dependency service or group failed to start.”
2. After enabling all the dependencies as you described in your comment however everything is working fine.
Thank you, it works.
Also, disabling a lot of processes has made my Vista 2 to 3 times faster, so it was worth the experimentation.

Followed DeeFer list but got,”Windows could not find Windows Audio Endpoint Builder” even after I started Plug and Play. So now what? I did get instuctions on how to start services with instruction about “local” and “network” but also a cautionary note about being qualified to make changes.

This worked for me, I only had to remove: “AudioEndpointBuilder” from the list:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Audiosrv
and in the DependOnService remove all entries except RpcSs and then restart your computer
(I left MMCSS)

I had problem of Audio service not starting and Power Options not selectable in Control Panel. I use Win7 and I checked with another computer reasons and found in Registry that following key and subkey was missing:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Power. What I did was to export from one registry the values to the computer that was not having this key thru a flash disk. And restarted the computer to find both working. For those who can’t do this import here are the values you should write in the registry manually:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Power

I have a problem related to Windows Audio service.
The dependencies i.e RPC and Plug&Play are working but the Windows Audio service does not start automatically.
I have to start it manually.
