Do the latest RME cards (fire face UCX, UC, UFX) work under Linux? alsa/ffado? Does anyone use the fireface 800 successfully with ffado?
hi,
The new firefaces (ufx, ucx) seem to be running perfectly well via usb2 under linux, with "class compliant mode", without drivers. But i have not tested it personally.
I have the UCX running in CC mode, Alsamixer has only one control, the master volume.
You need a Kernel with at least 3.8 to get audio over USB2 devices at all because of some bug in ALSA. The fix of the alsa /sound/usb/mixer.c is in kernel 3.8 which i have on the system. http://mailman.alsa-project.org/pipermail/alsa-devel/2013-January/058998.htm...
however the current kernel has some issues wich causes horrible crackles (I tried 44100 and 48000 Hz, they both give me different kind of crackles).
