The windows audio mixer is missing (control panel - sounds and audio devices). The Control Panel item opens, but everything is greyed out. This is obviously a WINDOWS OS issue, not the driver. Here are some facts...

1) The audio device (onboard RealTech HD) on my Asus P5GC 1333 Mother Board is installed and working properly according to WINDOWS Hardware Manager. (and has been uninstalled, and reinstalled with fresh drivers from the ASUS (motherboard) web site.

2) The WINDOWS AUDIO service is started. (and restarted, and turned off and rebooted, and turned off and uninstall the audio device then rebooted start audio service and install new driver)

3) When I run the ASUS / RealTech audio settings manager I get beautiful test sounds out of the speakers. Clearly, the audio device, and my speakers are fully functional. I would also assume that this means that the WINDOWS AUDIO service is running fine.

4) The windows sound icon does not show up in the systray, but it does show up in the RealTech Audio Systray sub-menu. However, when you click on it, an error appears stating that there is "no audio mixer installed."

 

As kind of stated above, I have done all the standard audio fixes.  Turning the Windows Audio Service off and back on (it was on all along).  Uninstalling and reinstalling the hardware and drivers in Windows.  Obtaining fresh drivers and installing those.  Attempting to use System Restore (it will not restore).  I even tried all these things in SAFE MODE.  

 

I was going to remove the board, start, shut down, reinsert the board and restart....However, it is "on board" audio.  So that is not possible.  Oddly, I do not see anything in the CMOS that allows me to shut down the on board audio.

 

The fact that I get sound out of the ASUS / RealTech audio settings manager tells me that the drivers and hardware are fine.  It is Windows that has the problem.  I just can't figure out what that problem is.

So I found how to disable the on board audio in the CMOS (BIOS).  Disabled it.  Started, restarted, installed driver from fresh ASUS download.

 

The problem is still the same.  Audio plays in the ASUS / Realtek Audio Manager, but no where else.  Device Manager says that the Realtek HD Audio is installed and working properly, but the Sounds and Audio Devices Control Panel Item still says that no audio devices are installed.

 

...is anybody out there.....

What's interesting is Asus specs out the audio as a Realtek ALC883, 6-CH High-Definition Audio CODEC but according to Realtek's site it's a 8 channel codec.

 

Have you tried installing the Realtek software here?

Yes.  I tried that one before downloading the one from the ASUS site.

 

I also did the uninstall, reboot, install, reboot thing with it.

 

I have been installing with the driver software instead of the windows driver wizard.

They are probably already started and set to Automatic but check the Plug and Play service as well as the RPC service.  I assume you downloaded and ran the Windows Audio Playback fixit as you posted you ran all fixit's.

 

Have you ran the directx diagnostic? That may give  you a clue. Also look at System under Event Viewer. Other than that, I don't have anything addititional to add.
