Unfortunately that doesn't work. Probably because I have not an Intel Atom based laptop but Intel Skylake. And I have following controllers:
00:05.0 Multimedia controller: Intel Corporation Skylake Imaging Unit (rev 01)
00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

Here is output I'm getting:
