The capture interface does not work, and the playback interface actually supports only 48kHz unlike what is advertised (44.1, 32, 22, 16, 8).
The only unknown here is if there are other devices that use the same product ID, but given that this ID is currently unknown, I would assume it is specially allocated for the nura headset.

Is there anything else I need to do? Get more testers maybe? I have reported bugs here before (and had a nice interaction with Takashi Iwai) but this is my first patch to this subsystem (I am an Intel/Nouveau/DRM developer).
For more information on how I got to this patch: http://www.mupuf.org/blog/2018/01/14/nura-headphones-on-linux/
