Windows 7: Suddenly no sound. "Failed to play test sound" Is this unsolvable?

Suddenly no sound. "Failed to play test sound" Is this unsolvable?

A few days ago we had a power outage. I don't have an UPS on my Win 7 64 bit Professional PC Dell Optiplex 780. When it powered up again I found I had no sound.

This is what my onboard sound looks like in device manager:



Is it odd to have that many devices?

Here are the things I've tried:
  • Went to Control Panel->Sound->Speakers->Properties. Everything says working fine. Turned on disable all enhancements. No sound. Went to advance. Changed format to DVD. Pressed test and received the "Failed to play test sound"
  • Went to services and restarted Windows Audio. No sound.
  • Ran 'sfc /scannow' from Admin command prompt. Said it found some problems and fixed them. Needed to reboot. Rebooted. No sound. Here's my CBS log file from this try (Dropbox - CBS.log)
  • Run virus/malware scan using AVGFree and Malware Bytes. No threats found. No sound.
  • Uninstall sound drivers, reboot and reinstalled them using the drivers from Dell's website for this model. Still no sound.
  • Booted Win 7 install disc. Chose 'Repair PC'. Windows said it found problems but couldn't fix it.
  • Ran chkdsk with the fix option. Found some files and repaired them. No sound.
  • Windows update . No sound.
  • Bought a cheap USB sound dongle. Installed drivers. No sound. Went into Control Panel->Sound->Speakers->Properties and got "Failed to play test sound" for the new device. You've got to be kidding me!!
  • Ran
    Code:
    dism /online /cleanup-image /restorehealth
    but get a error code 87 saying that restorehealth is not recognized in this context



I'm not sure where to go from here. I do not have restore points to go back to. Does anyone have any ideas on how to fix this? My family would be most grateful for your help!

In addition to a number of other files, the shutdown did a number on audiokse.dll.

I found this from the microsoft fixit-

AUDIOKSE.DLL – Microsoft Support

It doesn't say what to use to scan your registry with and it later suggests downloading and running paretologic. I couldn't get it to run but I only spent a couple of minutes with it.

Thanks for this. I did download that registry cleaner and just cleaned up the registry. It did find problems and repaired them. I did this next:

Code:
C:\Windows\system32>sfc /scanfile=C:\Windows\System32\AUDIOKSE.dll

Windows Resource Protection found corrupt files but was unable to fix some of th
em.
So something is definitely no good. I just remembered that I had cloned the original hard drive that this PC came with to the SSD I'm currently using. I'm guessing that the audiokse.dll on the original hard drive is not corrupted. Is it possible/advisable to copy this file over the corrupted one? Will windows even allow me to do this as administrator?

Hi dinki

You can try DISM again. Only the /restorehealth switch doess not work in Windows 7. Hence your error message.
Try:
Code:
DISM /online /cleanup-image

Gave this a try and I could have sworn I was able to run this before:
Code:
C:\Windows\system32>dism /Online /Cleanup-Image

Deployment Image Servicing and Management tool
Version: 6.1.7600.16385

Image Version: 6.1.7601.18489


Error: 87

An error occurred while processing the command.
Ensure that the command-line arguments are valid. For more information, review t
he log file.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

C:\Windows\system32>
Here's a link to that log file: Dropbox - dism.log

I can't thank you enough for your guidance and for trying to help!

Hello dinki,

When you run DISM, do you have admin privileges (elevated command prompt)?

Hi dinki,

Welcome to SevenForums!

As iko22 has pointed out, run it from an elevated command prompt:

Click Start.
  • In the search box type cmd.
  • Right-click the cmd icon from the search results under Programs and select Run as administrator.
  • The elevated command prompt window will now open.
I hope this helps!

Hi dinki,

I don't know if this will help but might it be worth a try!

Run an Extended Disk Cleanup [with ALL the options checked]. This gets rid of all the superfluous files etc.

I hope this helps!

Just tried the clean up and didn't make a difference. Sigh... Unsolvable?
