[1951F5G, Analog Devices AD1981, Green Line Out, Left] Pulseaudio fails to detect card

[grofaty]

I saw a help to report audio problem with command:
ubuntu-bug -s audio

I have no sound in Ubuntu 16.04. In System Settings | Sound there is empty list o output and input devices (see attachment). I did clean install couple of weeks back. Previously I have got installed Ubuntu 14.04 with zero problems with sound.

I don't know how to fix this problem.
By the way, I can fear audio well e.g. in youtube using Firefox browser.
