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.
