No Audio, cannot start Windows Audio Endpoint Builder service, RPC server unavailable

Anonymous

I had the audio functioning fine, then I checked off a few services that are safe to set to manual, and now I am having problems with my audio. I went over all the necessary services that need to be started and all of them are set to automatic and running except for the Audio enpoint builder service, windows audio service, and the creative audio service.

when trying to start windows audio endpoint builder service I get error 1722: the RPC server is unavailable.

I cannot start the windows audio service either. I get a 1068 error message: The dependancy service or group failed to start.

I tried changing the local system account log in info and now I'm getting a different error message: 1079 the account specified for this service is different from the account specified for other services running in the same process.

I tried uninstalling my sound card drivers (creative audigy 2), my onboard sound drivers (AC97) and reinstalling them both, no luck.

I am running Win 7 Ultimate 64

I am also having a problem with my USB keyboard going dead. the backlight stays on, but none of the keys will respond. I have to unplug the USB and plug it back in and wait for it to reinstall. It appears that if I don't use the keyboard for a while it powers down, but the lights stay on. I disabled USB power saving in the power profile and the problem still occurs. My mouse doesn't turn off, so I think it's not related to my power profile. It is a Saitek Gamers keyboard (USB).

Any help would be appreciated.

Thanks,

Alex

DCOM Server Process Launcher started, automatic

Plug and Play started, automatic

Multimedia Class Scheduler started, automatic

Remote Procedure Call (RPC) started, automatic

Windows Audio Endpoint Builder not started, automatic (error message 1722)

Update#2 I was able to get the right login info to get rid of the 1079 error msg.

I typed in NT AUTHORITY\LocalService and left the password blank.

now I get the same error msg as endpoint builder... RPC server is unavailable.

Edit# 3

I enabled power and everything started to work as normal.

except I still have the keyboard problem.

thanks,

I am guessing the problem with the Windows Audio Endpoint Builder is that you have disabled the Windows power management on Windows 7. For some reason, the audio services cannot start if power management is disabled.

I was going to install the APC Power Management software for my UPS and it requires that Windows Power Management be disabled. I disabled the service and rebooted the system and noticed that the audio services did not start. Trying to start them by hand gave the errors you mentioned. When I started the power management service, I was able to start the audio services.

Microsoft does not mark these as dependent services, but there is some relation. I know in Windows 7 that they were saying it optimized power utilization for audio and I am guessing that the audio services are looking at the power management to see what type of profile is in use. Since power management is not running, this is not available and the audio services terminate. Again, this is just a guess and I cannot find any definitive answers about this.

Power, RPC server and Audio are tied in together for one purpose:

It allows Microsoft to access your computer through the RPC in cases when Microsoft feels legally justified according to their EULA without fear of compensative Tort. Anyone with RPC, Audio and Power activated can have their computer rummaged through by at any time by Microsoft.

A large corporation or government server will not have audio running, but Microsoft can still access their software through the SQL and RPC if that's the case. However, anyone with audio running on a server doesn't have enough money to sue Microsoft for unlimited damages, and therefor Microsoft tied a nifty little backdoor into these processes to alleviate quite a bit of hassle for themselves.

I reset the power services about three times now

But for your case, wasn't it that the audio services were ON before you turned off power?

Because for me, I get error 126 with power services on specifically for Windows Audio Endpoint

I don't know if I may be making a couple mistakes here and there, but any dependents are ON and STARTED for each dependency for both Windows Audio services

Anyways, I'll keep trying the same thing but let me know I may be missing something or any recommendations on what to try. Thanks!

From the Control Panel, go to "Administrative Tools" and then click on "Services". Scroll down until you see the "Power" service.

Double-click that service to bring up the properties and in the General tab make sure that the startup type is set to "Automatic" and then click on the Start button.

You should be good to go now.
