windows showing no audio output device is installed

After a usual restart with my windows 10 PC (Lenovo P50) I am facing an issue with my audio

When I checked the sound settings it shows "No output device found"

My device manager also not showing anything related to sound

I tried manually installing the driver from device manager->Actions->Add Legacy Hardware. But that too didn't worked.

Below is my OS specifications

Any one facing this issue?

Reboot. Then go to: Control Panel -> Hardware and Sound

Under Devices and Printers, click "Add a device". This should scan your system for any unmanaged hardware. If your audio device is present, it will find it and add the driver. If it doesn't find it, then it is likely a hardware problem.
