HP COmpaq 8100 Elite Small Form Factor PC

[JB_USA]

I have several new desktops of this model purchased 60 days ago.  When I purchased them the sound worked fine on all of them.  Apparently an updated drive or something has now muted all of them.  I cannot start the Audio Endopoint Builder service or I get Error 1722, The RPC server is unavailable despite the fact that is it running,  and I cannot start the Microsoft Audio Service, I get error 1068:  The dependency service or group failed to start, which presumably is the former.  I have tried updating the audio driver, with no positive result, I have uninstalled the audio device and tried to reinstall that with no positive result.

Ideas, preferably solutions ?

Hello JB, can you let us know what OS and version you are running? Do you have all the windows updates? Also have you flashed the latest HP BIOS onto the system boards?

[JB_USA]

I have completed all of the Windows 7, 64 Bit  updates as well as all of the HP updates although I do not believe I have flashed the Bios with that update.  I will check on the Bios version, update if necessary and then report back.  Thank you for the suggestion.

I have updated the BIOS to current version on all similar model PCs.  No improvement in sound performnce on any of the three.  The PC detects connection of speakers to the PC but the speakers wil  not function and the audio services continue to be disabled.  System OS is Windows 7 Professional in 64 bit mode.  I attempted to start the Windows audio services and the error I get stated that the RPC server is unavailable.

Ideas?

Hi:

If you haven't done so already, and since you have tried everything else, the only suggestion I can give you is to download and install the latest Realtek audio driver directly from the Realtek site.

Accept the agreement. Download and install the second file listed which appears in blue.

I downloaded the Realtek audio driver as suggested.  The install seemed to work correctly and I rebooted the systems.  This updated driver did not resolve the problem, the audio services still will not start citing the RPC server is unavailable.

Ironically, the HP update software pushed out an updated RealTek driver which appeared on my desktop within minutes of installing the driver from the RealTek site.  The driver installed from HP did not resolve the problem either.  I guess that only proves that multiple versions of a driver that does not work will not improve the situation.

I remain stuck with this problem.

Sorry that didn't work. Sometimes new drivers are released in response to issues like yours or other issues.

I don't have any other ideas as to what could be wrong. So, I hope someone knows specifically what to do for the problem you are experiencing, since it apparently is not a driver-related issue.

I am now 2 or 3  steps closer to the solution.  No harm in trying to limit the possibilities.

I did a search on some of those error codes...Don't know if these are relevant from MS:

 error 1068. Has an automated fix it solution.

Error 1722:

Before you work with any of those, read this MS forum post which describes a very similar if not the exact problem. Read Steve Van Domelen's post about Windows Power Management.

Good luck!

With this, I am now completely out of suggestions.  :smileysad:

Solution !!

I had un-installed the HP Power management software that came with the PCs because we were encountering conflicts with network management and wanted to eliminate some factors.  Apparently the Windows power management service is disabled when the HP power management software is installed.  When the HP power management software is uninstalled, the Windows power management service is not re-enabled.  Once the windows power management service is enabled once again, the audio services work fine.  Apparently the power management issue is an undocumented dependency.  What a waste of hours this was.  I hope that at least others benefit from this solution.

Thanks for all suggestions.  As a result at least I have completely updated PCs for the moment.
