Description of problem: SND_CONFIG_BEBOB is needed to run many firewire audio devices. Please enable it. The driver is here: https://github.com/takaswie/snd-firewire-improve But a version is upstream already. (It also might be worth enabling CONFIG_SND_BCD2000 but I have no experience with this driver.) Version-Release number of selected component (if applicable): kernel-3.18.8-201.fc21.x86_64
This will be enabled in the next builds on the f21, f22, and rawhide branches.
