Solved Realtek Audio not working after windows update

[saherboy]

Hi everyone
I see a lot of related topics in your forum and I need your help in my case
I have the following PC
Compaq 500b mt with Core 2 Due CPU, E7500 @2.93GHz
64 bit OS
and both realtek audio and Nvidia HD audio
after some updates it is now assigned as the driver is installed and normal icon appear
when I try to play music window media player is says that (windows can not play this music)
and when I try to configure the sound in play back device it appears as default
I have tried almost every tip listed here
with no progress
system restore was good choice and now it is not working since I do not see old restore points
Please advice me and do you encourage me to make full format

Hi saherboy, welcome to Seven Forums.

What shows on your pc as in my image.

 

[saherboy]

Hi
Thanks and this is the condition

 

[Roderunner]

That, my friend, is confusing. I have never seen a pc with your sound setting.
Try right clicking Nvidia HDA and select disable then see how your sound performs.

 

[Dude]

Most of the newer video cards have HDMI sound, make sure realtek is the default device

 

[saherboy]

@Roderunner I have disabled the Nvidia HDA and same problem exist
@Dude Speakers is the default device, and it appears as in your image and when i try to configure and click test it say that (failed to play test tone)

 

[Dude]

Do you know which windows update that installed and caused this? If so you can remove it

:ar: Windows Update-Uninstall

Edit

You can try this too

1 Go to control panel
2. Double-Click on the Sound Icon
3. Single-click the Speakers to highlight them
4. Click on Properties (bottom right corner)
5. Go to the Enhancements Tab and Click on it
6. Now click "Disable All Sound Effects"

@Dude I have disabled enhancement and still not working
also uninstall all updates before some time and same issue

 

[Dude]

saherboy,

Try this Click the Start Button, type "services.msc" (without quotation marks) in the Search Bar and press Enter to start Services.

In the right pane, please check whether the Windows Audio service is started.

If not, double click the service. In the tab "General ", make sure the "Startup Type" is "Automatic". Then click the button "Start" under "Service Status" to start this service.

If it is started, stop it, then restart it

 

[saherboy]

It is already started
I have stopped it and start it over
no any new thing happen

 

[Dude]

Okay, I would run a repair install

:ar: Repair Install

 

[saherboy]

@Dude
It works for me
It is a long process and need Win 7 with SP1
very good solution
thanks in advanced

 

[Dude]

It is working now? or do you need a win7 w/sp1 iso?

 

[saherboy]

Thanks
It works

 

[Dude]

Good to hear
