So I recompiled FFADO with an already changed configuration file in the src compile directory and rebooted. Now the mixer shows the Focusrite (yeah!!!!) and I sent the info/registration that was requested.>> Now in Jack, I am unable to start Jack with Qjackctl, but it starts from the command line using;>> jackd -d firewire -r 48000 -p 512>> So I am sending this email and can't wait to play around with Mixbus!!!>> Will report back soon!>> Thanks so much!>> Best,>> Eric

I went back through the install log (I usually make a copy for stuff like this) and this is what I came across...
I couldn't find all the prerequisites ('pyuic4' and the python-modules 'dbus'
and 'PyQt4', the packages could be named like dbus-python and PyQt) to build the
mixer.
Therefor the qt4 mixer will not get installed.

Perhaps this is what your referring to?  I thought I saw somewhere that the mixer was 2.1.0 and I paused for a second to wonder why, but it quickly passed.

If it is friendlier, I will certainly re-re-compile! :-)  Thanks.

Will check it out for sure, the 95-jack file priority level is 70.  I will try it raised to 99 in the meantime.

Once again, thank you very much for your help!
