It does not use ffado at all but rather the built in ALSA firewire module 
stack. This means, do not try to use ffado-mixer, bad things will happen. 
Use alsamixer or the qasmixer (which is GUI based) instead.

So far, anyone I have talked to that has had problems with fw devices in 
the past few years, since fw was added to ALSA, has had those problems 
because they tried to use ffado bits without first removing the alsa bits.

So I am wondering how many people have firewire devices that have found 
the alsa drivers for firewire, when used correctly, don't work for them.
