Hi ZTube, did you follow the setup instructions described here? https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/sound/usb/mixer_scarlett_gen2.c There's also a bug with the saffire range currently that prevents a record stream to be started after a playback stream. I suspect the bug is related to the usb audio driver and the handling of implicit feedback mode, but I haven't had the to confirm this yet.
