No Audio Output device installed error
Hi
My inspiron 15 3520 running windows 8, the audio has stopped working, just showing that no audio output device is installed. If I go into the device manager , and look under sound, cirrus logic high definition audio, and high definition audio device, both have yellow !, with an error showing of code "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
Now I tried uninstalling both through device manager, rebooting and re-detecting but same problem. I have downloaded latest drivers from Dell, same problem. If I reboot the laptop with digitally signed drivers disabled, audio works and everything is ok. Only problem is as soon as you reboot, back to square 1, no audio output device installed.
So seems to me there in an issue with dells drivers not being digitally signed or being rejected, and I do not know of any way of permanently disabling signed drivers check.
Any help appreciated.
TIA

Something has changed but it seems to not be the audio driver, because the Cirrus Logic driver version was released over a year ago and you were using it okay before the problem arose. Try using Windows System Restore to see if that will undo the problem. Type "system restore" into the search box.
Another route would be to install the native Windows audio driver. To install the native driver, remove the Cirrus Logic driver. Open the Device Manager and expand the Sounds Controllers section. Right click on the Cirrus Logic and select to uninstall. Put a check mark in the option to delete the files, and then ok. When you reboot, Windows will either install its own native driver or a Cirrus Logic driver if there were any other versions on the hard drive. So go back to the Device Manager and check for a Cirrus Logic driver. Keep uninstalling & rebooting until Cirrus Logic no longer appears under Sound Controllers and "High Definition Audio Device" appears in its place.
At that point you will be using the native Windows driver, so if you get the error with it I would think there is some problem with windows, or maybe malware. If you don't get the error with the native driver, go ahead and install the Cirrus Logic again and see what happens.
