It's question for pulseaudio. For the legacy ALSA code in PA, you need to 
create profile, mixer path and udev rules. The probe mechanism used in PA 
looks for the volume controls and path switches (kcontrol) API to determine 
the device name. If not found, the generic name is used.

It's better to finish the UCM support for this hardware:
