====== rme fireface ucx ======

===== General =====

The [[http://www.rme-audio.de/en_products_fireface_ucx.php|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 but works with Ubuntu-Studio.

===== 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 [[https://ubuntustudio.org/ubuntu-studio-installer/| Ubuntu-Studio installer]] everything works with Jackaudio (QJackCTL).

Listed audio channels in Jack correspond to: 

CH 1-8 => Analog 6.3mm Jack Out


CH 9 - 10 => Spdif


CH 11 -18 => 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.

[[ https://wiki.archlinux.org/index.php/JACK_Audio_Connection_Kit | see here.]]
Get working scripts [[ https://github.com/magdesign/PocketVJpro/tree/master/scripts/jackscripts | here.]]

We figured out that custom routings are only loaded when QJackCtl is started from GUI rater than activated from command line only.
