"No audio devices are installed" issue in Windows 10

I am running Windows 10 Pro on a Dell Precision 5510. My BIOS information lists my sound controller as "Realtek ALC 3266". But a couple of days ago I suddenly stopped getting any sound. When I go to the "Playback" tab in the "Manage Audio Devices" screen,
it says "No audio devices are installed."

In the Device Manager itself, under "Sound, video and game controllers", I can see an entry for "Realtek Audio" if I check "Show hidden devices" in the "View" tab. But it is greyed out.

I have tried running Windows 10 troubleshooting but it can't detect any problems.

Suggestions?

no audio output device installed

I've tried every step that was suggested, still getting no audio output device installed.

 

No audio devices detected


So, after upgrading to Windows 10, my computer no longer detects any audio devices.

Device manager only detects nvidia hd audio
Playback devices only detects nvidia hd audio

After installing realtek drivers, realtek is nowhere to be found - no icon in system tray, no realtek device in device manager etc.

USB headphones work fine, just dont have any support for rear panel audio jacks, have disconnected front panel audi connector, installed fress win10 copy, still nothing
