This is a "must have" piece of sotware for runing FIREWIRE interfaces. Problem is that, LM needs to update everything related to FFADO to the 2.4.8 Version. LMDE is already runing the 2.4.7 version. Again, the only problem now is that LM Cinnamon, MATE & XFCE need to update the version to the newest one. RME Hammerfall FiREFACE 800, does not work at at all with the version available at the LM repo
