rme fireface ucx
General
The RME Fireface UCX is a professional interface with 18 i/o channel (8 analog, 2 mic preamps), MIDI, S/PDIF and ADAT. It has both Firewire (400) and USB 2.0 (class compliant).
Its not officially supported under Linux.
Software
In CC (Class Compliant) mode the RME Fireface UCX works out of the box without having to use a patched kernel or flashing some firmware (tested with USB connection in Ubuntu 18.04 LTS).
ALSA will see only one channel, but after installing QJackCtl from Ubuntu-Studio installer everything works with Jackaudio.
Listed audio channels in Jack correspond to:
CH 1-8 โ Analog 6.3mm Jack Out
CH 9 - 10 โ Spdif
CH 11 -18 โ Adat (Tosink)
You might run some pre-start and post-start scripts from QJackCtl to get rid of some pulseaudio standard routings to the first 2 channels.
See here: https://wiki.archlinux.org/index.php/JACK_Audio_Connection_Kit Get working scripts here: https://github.com/magdesign/PocketVJpro/tree/master/scripts/jackscripts
We figured out that custom routings are only loaded when QJackCtl is started from GUI rater than activated from command line only.
