So this is part two of a solution that I had to discover on my own after hours and hours of searching for the answer to a problem that had a very obscure solution. [ See Part 1 here. ]
So after the first fix which was repairing the netprofm service in the registry, I was left with no audio. When attempting to start the Windows Audio service, I got the error very vague message of “Endpoing is a duplicate.” So I searched through the services in the registry looking for something in the AudioSrv key that may be causing the problem. I noticed two keys which were “AudioEndpoingBuilder” and “AudioSrv”. Everything seemed to be correct except for one thing.
(UPDATE 4/20/2015: For an automatic fix, look below at the bottom of this post for download links and an explanation on my registry exports. No knowledge of the registry is required.)
For the manual fix and details, read on…
Navigate to HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Services -> AudioEndpointBuilder -> Parameters
Check the ServiceDLL data, on the problem system it was:
%SystemRoot%\System32\Audiosrv.dll
It should be:
%SystemRoot%\System32\AudioEndpointBuilder.dll
There didn’t seem to be any problem with the AudioSrv -> Parameters -> ServiceDLL data as it was already set to it’s correct value of :
%SystemRoot%\System32\Audiosrv.dll
So if yours is off, I would go ahead and change it.
After a reboot of the system, all sound was back and the services were started with no errors.
I have, as of writing this later, come across these combined problems twice now. The first time took me hours if not a couple days to finally discover these solutions. The second time I knew exactly what to check.
Both computers where Dell systems. One was a laptop, one was a desktop. Both were lower end consumer grade desktops. Not sure what models. I don’t really know what software was in common. I wish I had taken a log of both systems to compare any similarities. If you end up finding this useful, try to grab some information so we can attempt to track down what is causing this odd change in these two keys. I have a feeling it may be something to do with the factory image they use when creating these particular problematic systems. Possibly a bad driver or update that was pre-installed.
Anyways, I hope this helps someone else as it has me on two occasions so far. Please feel free to comment.
UPDATED 4/20/2015: I have been asked to provide further information on how to edit the registry. My stuff on here is for self-help techies with the assumed knowledge of what I know. However, for those that may need help in editing the registry, I’m attaching registry exports that you can execute to automatically fix the registry keys mentioned in both of these posts. I’ve included an export of each of the mentioned keys as well as one combined export. It honestly won’t hurt anything to run the combined file regardless if you only need on or both fixes, but if you prefer to only fix one of them at a time, go ahead and download the individual keys. To use the downloaded files, just save the REG file to your PC and then just run it like a normal setup file. You may want to disable your antivirus. You may also receive a UAC prompt asking for permissions to make changes to your system, you want to be sure to allow this change. You will most definitely then receive a message from Registry Editor warning you about changing or deleting values in the registry, click Yes to continue. You should then relieve a message that the registry key was added successfully. After applying either of these registry keys you will need to reboot your computer.
Keep in mind, after making these registry changes, you may still have issues that this fix just isn’t the root of. I can’t provide Much else tech support via these forums, but if you have issues running the registry export, then post on here and I’ll try and help you out a bit more with my fix.
Downloads:
- Netprofmsvc.reg (Download either this one…)
- AudioEndpointBuilder.reg (…and this one.)
- Combined.reg (Or download this one only.)

1 2 3 … 18 Next »Now that I've read part II as well as part I... Have now done as outlined above, but alas, still no sound. Any further advice you may have would be appreciated.
David, please look back at the first post as I have updated a previously incorrect path. Hope that will solve the issue.
Having same problem that was dicussed. Error 0X800706cc: The end point is a duplicate.
I am an old man totally computer illiterate. I've already tried posting on here three times, have no idea where they went.
I don't even know how to get to registry or what it is. Can you break all this down so I can follow it please? It looks like everyone is very happy with your solutions. Thank you
Hello, Marv. Are you still having this issue?
Marv, please look at my new registry export downloads above if you are still needing assistance. You'll be able to just run those files without needing to know the registry. Sorry for my late responses.
How do I run those files you posted? When I press on them they open in another window and I don't know what to do from there. Thanks in advance, you are helping a lot of people.
David K., try right clicking on the download link and look for Save As or Save Link As. The file should download as a .REG file. If you still have problems then open them as you did before to see the code. Then open Notepad on your computer. Copy and paste my code into Notepad and then save the file to your desktop as “whatever-name-you-want.reg” with quotes – – Windows will remove the quotes in the file name, but using quotes prevents Notepad from saving the file as name.reg.txt and giving the wrong extension. After you have done that, just double click on the new .REG file that you saved.
Hope that will help you out.
Well I ran the file without having to paste it to Notepad and It apparently worked. I can now go on Control Panel without it freezing. So that's fixed but the audio still doesn't work.
hi there,, I have tried all your tricks but then when I started running the window audio end point it says that it cannot be run on a local computer. how do I fix that?
Thank you so much I have not had audio in about a year. I looked for other fixes with no success. I followed your instructions and I also restarted my computer. When I restarted I had a mute instead of an X
I'm having the same issues with the control panel and with my audio using Windows 8/8.1. I tried your control panel solution, and it's as if it somewhat worked, just not quite. The control panel still froze, but the info bar at the top of the page turned from white to green before freezing, which is more than it was doing before and makes me think we're on the right track.
I'm working off of a Lenovo laptop (don't worry, I've already checked for superfish!) so I wonder if the formula to fix it is maybe just a bit different for each brand of computer?
I haven't tried fixing the audio yet; wondered if I'd run into the same problem.
Any suggestions?
Thanks!
Double check the registry key that was mentioned in my first post. I recently updated an incorrect path that I had mistyped originally. Make sure that is correct. Also go ahead and ensure the above registry paths are also matching what I have. There really shouldn't be any reason that these paths should be different from computer to computer as these are Microsoft services, not OEM implemented services. If yours are different, make sure to change them to what I have provided.
I've had this problem and the one detailed in Part 1 since October, read some things about it having to do with AVG quarantining some Update files, have tried every fix imaginable short of wiping the machine and reinstalling OS to no avail. This worked perfectly and saved me tons of time. Thank you so much. System was Lenovo Y50 with Windows 8.1.
I can't thank you enough for these posts, saved my nerves.
Do you know why this happens in the first place? Is any side software causing these changes?
OH MY FRIEND FOR LIFE!!!
That was exactly it, both the netprofm and the audio endpoint were set wrong. My personal debt to you is considerable. Is there anything I can help you with? Email me!
I've spent the last 12 hours safe-mode-try-no-safe-mode-try-no, pulling my hair out. So now -- what did we *do* to cause it? I had no updates except an office 2013 one that i rolled back. Do you suppose that was it?
Wow. Thanks again.

My sound issue and control panel hang/freeze started after my Lenovo Gaming Laptop started making the well known yeti/chewbacca sound, and crashed/restarted in the middle of me watching a "Keeping Up With The Kardashian's" episode. (I know, I'm embarassed). So I think the Kardashian's are all to blame for this issue. ¯\_(ツ)_/¯
Awesome! I've been looking for solutions for 2 days and this was the only one that worked, i was about to give up and format my windows.
Thanks a lot!!!
I had issue with both and this corrected totally. My problem seems to have been connected to attempt to use Avast anti-virus. Upon download, Avast disabled Google search. Upon subsequent uninstall, control panel froze, Internet explorer was disabled as was audio. Worked on it for a full day before I found this post and was able to repair. Don't know how you found solution to begin with but I certainly am thankful. Could have done w/o explorer and was able to work around control panel somewhat, but sure am glad to have my audio restored. Many thanks again!!
I never write on these things, but I just wanted to say that you saved my computer. It recently went wrong on the last update a week or two ago. I own a Microsoft Surface Pro with Windows 8.1. It started with apps not working in the metro (I noticed dropbox, netflix, and the store failing). Then later it was hanging on restarts. When I tried to address this with additional updates, the control panel and anything related to it would hang. I also noticed that today, Microsoft Word was taking a long time to let me save then eventually it was refusing to save documents.
I applied your recommendations. I've played with the registry key on a few occasions only with good adult supervision. I did step 1 and step 2. Everything works now. You saved me.
So thank you again.
Hi.
Thanks for your post, I did exactly as you stated on both parts (including correction) and although it fixed my control panel, I still can't get my audio service running. Any suggestions?
Thanks :)
Tried it, worked perfectly. Thank you SO much. I've tried installing and reinstalling drivers and didn't want to refresh my laptop just because of a broken update.
Funny thing though, both me and my friend have a dell laptop and we both updated our lappies AND had our audio problems the next day. I have AVG installed but I'm not sure what anti-virus he has. But, we cannot ignore the fact that this is major bug and needs to be handled ASAP.
