Realtek HD Audio on-board GA-EX58-UD5 no longer working

Thanks zcomputerwiz,

The DCOM solution you have provided is exactly the steps I have taken to resolve the issues so far. Not seeing any DCOM issues currently, but will use the same process if any appear again. It's very intermittent when these DCOM errors appear, as I had them one day, but the next day after rebooting they had disappeared without me doing any fix. Anyway, let's cross that bridge when it comes to it.

With the Component Hive, this is now no longer in the HKLM registry. So although it was saying it was corrupt and had been fixed, now no event is presenting, as the HIVE is not even loading. So far, this has not prevented me logging in, or doing work on the PC, and I can load the hive manually every time, but this doesn't persist after a reboot, so there is some corruption preventing it behaving. Again, happy to wait for your help on this element.

As soon as I get home tonight, I'll perform the procmon trace for test tone, and I'll upload accordingly. Thanks again for persisting. I've learnt so much so far.

For the DCOM errors, try following the instructions here: Application Specific Permissions Settings Do Not Grant Local Launch ...
The components hive being corrupted then recovered is a problem, sfc and other tools will not function correctly if it is has inconsistencies - I won't be able to address this right now.

I would like to try and trace what exactly is occurring when the test tone fails to play.
Follow the instructions here: How to Capture a Process Monitor Trace, start process monitor, attempt to play the test tone, then stop collecting data (CTRL+E) immediately after you receive the error.
Save and zip up the pml file then upload it with your next reply - I'll see what I can find.

Here is the link to the zipped up procmon log. https://www.sendspace.com/file/3tzesf
 
Run regedit and navigate to
Code: 
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{50aeb69a-858a-462a-9904-3a7cbe0e8ee6}\FxProperties\
Create a new DWORD named
Code: 
{1da5d803-d492-4edd-8c23-e0c0ffee7f0e},5
Set the value to 1.
Do the same thing for
Code: 
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{fb033e73-3cb8-4e0b-8b00-ae561bf606bd}\FxProperties\{1da5d803-d492-4edd-8c23-e0c0ffee7f0e},5
Reboot and try to test audio again.

Please export the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\ registry from your working Windows 7 install and the one with the 'failed to play test tone' problem and attach them with your reply.

I should have known that since you get the same message with the sound blaster device... so it has to be something with the audio services, not the drivers or audio settings.
Try this: Disable UAC Windows 7

Turn your speakers up and reboot. Do you get the Windows startup sound before it logs in?
 
Disabled UAC, rebooted, no sound, tested audio, still get the same error "Failed to play test tone". Also no Windows Startup sound before logging in. I have now re-enabled UAC. Please advise if you need it to remain off?
 
From an elevated command prompt type the following commands and press enter after each:

net localgroup Administrators /add networkservice

net localgroup Administrators /add localservice

After they complete, reboot and see if you have sound.
Remove the two service accounts from the Administrators group by typing the following commands in an elevated command prompt, press enter after each command.

net localgroup Administrators /delete networkservice

net localgroup Administrators /delete localservice
 
Drat.

I'm all out of ideas.
I think we've exhausted everything short of a repair install (in-place upgrade) at this point.
 
It's a Win 7 Ultimate, signature edition, Storm Le Ballam, (not for resale). I get the following: Error
We encountered a problem with the validation request. Please assure your product key is for a product supported by this site and was entered correctly, then try your request again.

Does that mean it is equivelant of OEM?
