"lspci -nn" is "Subsystem: Mark of the Unicorn Inc Device [137a:0008]"

boltctl also recognizes the unit.

The audio device MOTU 1248 is attached/connected by cable by Thunderbolt 3
on a iMac 18.2 2017 running Fedora 27 x86_64 Gnome 3.26.2 (runs perfectly on
a iMac 2017 Retina 21,5).

Which kernel drivers and modules are needed/available to use this device as
an audio device?

How to have this audio device listed in PulseAudio?

Please advice. Thks.
