"Windows Audio Endpoint Builder" service will not start

[SuperClocks]

The audio services worked fine at first. But after optimizing the system for gaming and security, the "Windows Audio Endpoint Builder" service fails to start. It gives the error: "Error 1722: The RPC server is unavailable" This is required for the "Windows Audio" service, so I have no sound now. Does anyone know the cause of this error? Here are the services that I am running...

Application Experience: Manual
Application Information: Manual
DCOM Server Process Launcher: Automatic*
Group Policy Client: Automatic* Grrrrr
Human Interface Device Access: Manual
Plug and Play: Automatic
Program Compatibility Assistant Service: Automatic
RPC: Automatic*
RPC Locator: Manual
RPC Endpoint Mapper: Automatic
Task Scheduler: Automatic* Grrrrr
Themes: Automatic
User Profile Service: Automatic
Windows Audio: Automatic (not working)
Windows Audio Endpoint Builder: Automatic (not working)
Windows Driver Foundation - User-mode Driver Framework: Manual
Windows Installer: Manual
Windows Management Instrumentation: Manual (On for nVidia nTune)

Should I be running any additional services? I skipped Vista and am still using XP. And although I know the bare minimum services for safe internet use, I am not interested in doing so. I just want to benchmark some games Thanks in advance!

I'm having exactly the same issue. It must be an undocumented dependency.

Hi superclocks, are you running windows xp?

 

[Chappy]

Don't mess with services, doing so can cause such weird issues as this. The service tweak sites that list all these "recommended" service configurations all fail to tell you how little resources are saved in truth, and how many unexpected errors you may receive. We tested this extensively years back and it's just not worth it...

Now, this is a Windows 7 forum and not many (if any) users here are still running XP even as a dual boot, but we can still help you out. Maybe you might wanna try loading a W7 copy in a dual boot and give 7 a whirl, you just might LOVE it...

Set your services back to their Default state, that may solve your issue.

I've got the same problem. The thing is I never even messed with services in this OS - and all was ok until todays updates after which sound just stopped. And then - look the first guy's post.
Creative Audigy 2
Windows 7 RC1

POWER fixed it

Concur with the guy that said he turned back on the "Power" service and it started working.

I had set that to manual last night and after rebooting my most of the audio services would fail to start. I started the "Power" service and then my audio services would start and I have sound again. Set "Power" to automatic and rebooted and it's still working.

So thank you very much sir!

agree with the two guys above. I ran into the same problem tweaking which service to run or not. When I re-enabled Power (after trying a ton of ways to renable it with other services), my audio, mic, etc came back on.

Saw BerggreenDK's fix, and it worked for me.... Remember to LEAVE POWER ON

Audio not working

Fix:

You probably disabled or stopped Power service ,set it to automatic and start it, if it doesnt start on first time try it to start again or put it on Automatic and restart PC.

Then your Audio services will work (start them) and whoola music is playin again.


Tx BerggreenDK

ps: I tried restore point and set it to two days ago, but it did not fix problem,
thats wierd.

Turning on power service worked for me

I've been searching for a solution too. I had disabled quite a few services myself and was starting to re-enable them again.

When I came to the POWER-service (C:\Windows\system32\svchost.exe -k DcomLaunch) and re-enabled that one, suddently my onboard RealTek ACL888 turned on and enabled the ports as expected.

And all my chat/sound programs suddently was able to use them.... wooohoo!

Im in your debt BerggreenDK,
For almost 3 weeks now, ive been having problems with various windows services. I had tried everything I knew to try to get the audio service on and nothing worked until I tried your suggestion.
Sound came back on straight away, still got a few more issues but at least I can some tunes on while I try and fix them.

Thanks again

Enormous! enable de power service resolve the sound problem "end point..audio service ." générateur de point de terminaison du service audio (i'm french) !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I've looking for many things and it was so simple

Thank you all

 

[flemur13013]

Same here: Audio services wouldn't start until the power service was started.
(Windows 7, realtek)

Only made an account to say I'm very grateful those that figured out the Windows Audio service depends on the power service. (whole reason I made this account was to say thank you)... so thank you.

(and yes.. MS should be ashamed of their error reporting - it should scan the current configuration of services and report back all potential causes but miserably fails to.)

Audio service won't start and Power service is missing

O have the same problem described here, no audio, except that when i try to turn on the power service I get "Error 126 specified module could not be found" Does anybody know how to handle this extra step?

Thank you in advance for any help.

So I cannot find the svchost.exe. What does this mean?

Please help. Having the "No Audio Output Device is installed" problem.

Thanks.

Created an account to say: thank you. Had the same problem, fixed by restoring the Power service.

Sam Ting here.
Created an account JUST to say...

I went approx 3 yrs with no audio from my "main" machine.
With zero recollection as to what occurred way back then, I spent 20 mins TOTAL to fix it. POWER service!!
And that included slogging thru the TechNet forums and those "take these 23 steps" non-answers from the MS answerbots.

So, Thank you, from 2016.
