[SOLVED] Windows 7 audio gone.

I think it all started when my Win 7 system drive started to go bad. The first thing I noticed (in addition to the disk errors) was that I no longer had audio and midi. I have a specialized audio driver/interface that is still working but everything else is gone.


I'm running 64-bit professional on a home built machine.


The Windows Audio Endpoint Builder service will not start, which keeps the Windows Audio service from starting. If I try to start the Endpoint Builder manually through services.msc, I get "Error 5: Access is denied."


sfc /scannow reveals that MMDevAPI.dll.mui, MMDevAPI.dll, and AudioSes.dll have problems, but it can't fix them. I'm assuming that's why the Endpoint Builder service won't start?

Sadly, I have to confess that I may have made things worse. I grabbed the above two dlls off a web site and tried to do some voodoo Take Ownership to copy them over the existing files that appear to be damaged. I was at least partially successful but I realize now that I may have simply created more problems. I have restored ownership to TrustedInstaller, as far as I know. But then again that also means that I restored ownership to illegitimate files.

I've tried uninstalling and reinstalling my various audio drivers to see if the files get replaced but nothing doing.

This one is way beyond my meager abilities. Any advice/next steps?

Thanks for all consideration!
 
Hello, and welcome to Sysnative!

Thanks for letting me know the past history & the previous repair attempts. I'll get the files patched up and a repair done on the permissions/ownership.


Please run sfc /scannow from a command prompt, then follow the posting instructions as linked above so you can upload the CBS logs here. Make sure to upload the logs *after* performing the sfc /scannow.

Thank you so much! Quick question--do you need the whole cbs folder (including cab files--looks like about 15 mg zipped) or do you just need cbs.log?
 
Hello again :)

I normally ask for all of the files including the cabinet files, because I sometimes need them after looking in the main CBS.log. However, after looking in your log, I don't need them from your machine so all's good.

SFCFix Script

Warning: this fix is specific to the user in this thread. No one else should follow these instructions as it may cause more harm than good. If you are after assistance, please start a thread of your own.

  1. Download SFCFix.exe and save this to your Desktop.
  2. Download the file below, SFCFixScript.zip, and save this to your Desktop.
  3. Save any open documents and close all open windows.
  4. On your Desktop, you should see two files: SFCFix.exe and SFCFixScript.zip.
  5. Drag the file SFCFixScript.zip onto the file SFCFix.exe and release it.
  6. SFCFix will now process the script.
  7. Upon completion, a file should be created on your Desktop: SFCFix.txt.
  8. Copy (Ctrl+C) and Paste (Ctrl+V) the contents of this file into your next post for me to analyse please - put [CODE][/CODE] tags around the log to break up the text.


Then re-run SFC, let me know the result from that, and re-test your sound.

Richard, I am deliriously happy! Thank you so much!

The fix appears to have run without errors and when I re-ran sfc, it finished with this message: "Windows Resource Protection did not find any integrity violations." All of my audio services appear to be back! After I finish this post I'm going to make an image of the disk! :-)

Here are the results of your script. Please let me know if you need me to anything else. Oh, and did I mention how grateful I am?
