Windows 7: No Audio or Power Services after ArcGIS Update

19 Dec 2018   #11

Windows 7 - 64 Bit
Update after IT

After I got IT to change the Windows Audio Log On to "This Account" and Local Service using the main Admin account Password (it wouldn't work with just my local admin password), then we started the service and it worked finally.

So to sum everything up:

The cause was unknown, but happened after a program was installed to update my current software and the next day I clicked on the popup in the lower right to change my password and discovered some memory errors appearing after on my programs and the Internet was acting strange, so re-booted.

Checked what I had researched, that in Services, the Power Management, Windows Audio and Windows Audio Endpoint Builder were all stopped.

I was not able to open Power Management in the Control panel either. After using that Autoruns64.exe program you suggested, found the "Power Management" in the entire list and tried to locate the file it was linked too without success.

Looked in the System32 folder and found that the umpo.dll was 0k. This was the dll linked to the power management. Also found that PlaSndSrv.dll was also 0k, but that doesn't seem to actually have any effect on anything as far as the sound goes after it was repaired.

Ran the System File Check SFC /Scannow from Admin Command Prompt and it fixed the umpo.dll error.

This was able to sort of start the Power Management. However, awhile back when trying to fix the issue, I read if you put the ImagePath name for power [HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> services -> Power] in the registry in quotation marks "%SystemRoot%\system32\svchost.exe -k DcomLaunch" the article said it fixed people's issues with the sound. It may have not been for Win 7 though, I forgot to remove them after doing that test.

After removing them. I re-booted to find that Power Management now started, Windows Audio Endpoint Builder started, but the audio couldn't be started because the Log On for Windows Audio in services was set to Local System Account and it should have been set to This Account in the Log On tab. This Account needed to be set as "Local Service" which you can add from the Browse Button. Admin again had to use their password as my local Admin password didn't work.

Started the Windows Audio again from Services and it finally updated and corrected the sound issue without having to re-boot.

Problem finally solved in case this ever helps anyone still using Windows 7 like we are...

I think I could have simplified the whole issue being to just check the System 32 folder for any 0k files, especially the umpo.dll and that maybe have been easier :)

Or just run sfc /scannow next time?

Or that. Though I still have that "PlaySndSrv.dll" which I have no idea what it's for that's 0k. Seems like it would have something to do with the audio, but not having any issues now with it so who knows. Also sfc /scannow didn't notice it at all either.

Maybe it's just a left over dll from an older audio update or something and no longer is meaningful...
