Windows 10 Unable to fix - "No Audio Output device is installed"

[npnpnpnp]

Got "Not Audio Output device is installed" error message since Oct-2019 update. I tried updating drivers but didn't help. Appreciate any help on this.


"Intel® Driver & Support Assistant" didn't detect any further updates on Drivers.

Ran "Troubleshoot->Get up and running->Playing Audio->Run the troubleshooter" many times, just asks me to restart at the end of the troubleshooting.

Observations:

Intel nuc has audio aux pin in the front. when i plugin speaker pin, i see a popup from RealTek. I've attached the screenshot for your reference. Not sure why it shows Analog, Back Panel as the port.





From the device-manager, I see audio drivers listed in two places.





Audio inputs and outputs->Speakers (Realtek High Definition Audio)




Sound, video and game controllers -> Realtek High Definition Audio
