Sound stopped working

[SailingNut]

Hi,

I have a quite odd problem. I have an Abit AB9 Pro mobo with a Realtek sound chip on it. Earlier today I rebooted my machine and when it came back up Windows told me I didn't have a sound card installed.

I went into device manager and I saw that under "Sound, video and game controllers" that there were 5 NVIDIA Sound devices listed with the exclamation point icon.

I then deleted all of them and had device manager re-scan for hardware changes. It then failed to properly install the drivers. I then rebooted and disabled the audio on the mobo , deleted the devices from device manager, rebooted enabled the audio & let it reinstall. Still nothing working, but now it does show "High definition audio device" instead of the NVIDIA device.

Any ideas on how I can go about fixing this? Thanks for all input!

Go nvidia downloads website search for the nvidia audio driver there.

or check this out see if this is what your looking for;

you wont get these drivers through windows update you will need to go to the nvidia website and search that way.

The problem is that it's NOT an NVIDIA chipset.

It's a realtek chip for audio. Somehow Windows thought it was an NVIDIA chip.

 

[HannibalUK]

Also if i got this correct you uninstalled or deleted the high def audio device, the other audio device was probably something like realtek high def audio????????????

 

[Ponmayilal]

The best I could suggest is to download the relevant motherboard drivers from manufacturer's website.

have you tried to manually download the realtek high def audio driver and install it that way?? it will uninstall old one first then you will need to reboot then hit the realtek installer again to install it.

then find the nvidia audio driver.

Realtek

Thanks for the link! I really should have tried that first, but I just couldn't get past the fact that it stopped working throught a reboot and I hadn't changed anything related to sound.

Unfortunately, that did not solve my problem. BUT, it did get me to look into it a bit deeper and the "problem" with the device is "Windows cannot verify the digital signature for the drivers ... Code 52".

I also see another driver with the same problem that I think should definately NOT have this problem. Under "System Devices" the "Plug and Play Software Device Enumerator" driver also has the "code 52" error.

Any ideas what might have gone wrong to cause this and how I might fix it?

HannibalUK,

I did look at the link you gave me but could not find any information that appeared to be relevant. It was talking about Windows 98 SE.

Did I completely miss something?

Suggestions:
1. Do you have a system restore point to a point before this problem appeared?

System Restore - How to use

2. Since the problem is unusual, try system file checker.
Oh yes, please read this tutorial from start to finish.
System File Checker - SFC /SCANNOW Command

3. Go into device manager, disable and Delete the driver. Shutdown. Power On.

4. Let's let Microsoft try:
MS Fix it Center Online
MS - Windows 7 Solution Center
No sound in Windows

5. Did you maybe, very recently, install some new software?

Thanks, I tried all of the methods you recommended (except the restore point because I don't have any recent ones. I know BAD computer owner!) and unfortunately none of them worked.

The root of the problem seems to be that Windows cannot verify the digital signature of the driver files. When I ran the Fix it troubleshooter for audio, it didn't detect that I did not have sound drivers installed. It seemed to think that everything should be working just fine. So, it seems that the signature problem is preventing Windows from loading the driver.

The only thing I did recently was to install 2 Windows updates. Neither of the updates required a reboot and the sound worked just fine after installing the updates. I just decided to reboot afterward to "be safe." That didn't go so well!

Next step:
Repair Install

 

[SailingNut]

Thanks to all for the input!

The repair install seems to have worked and resolved a few other issues I was having.

 

[karlsnooks]

Great! Glad to hear that all is well and that we could be of assistance.

I had this issue come up when I installed my GeForce drivers. It gave the option to install "Nvidia High Definition Audio" Since the card has HDMI, I figured it was for that, but it replaced my realtek drivers with Nvidia ones.
