Be aware that 41000 is not a valid sample rate 44100 is. Also in modern kernels after 4.5 there is alsa FireWire support for many devices YMMV. So to run without ffado you would use alsa backend. Also check, if you are using ffado, that the alsa FireWire drivers are not loaded or may interfere with streaming, good luck.
