Hello.

Yes, I have read the mails you have written in the past concerning the issues with FunctionBlockEnhancedMixer, etc and I' m aware there is some enhancement potential available in the ffadolib... 

With "passtrough" I mean a libffado compatible way of communicating directly with my device for the mixer function, without incourring in the standard problems of having different pieces of software driving one device. Maybe this is already ensured by the Firewire protocol stack in itself, but as I'm completely new in this field, and I have some experiences with other types of bus that are leading me to be really prudent, I'm trying to understand which could be a viable approach if I would try to use the mixer (assuming it is enabled in the device, I will have to revive a Windows box to verify with the official software)

Tnx again.

Marco
