I guess this isn't a PM (not marked as off-list), hence I reply to the
So you've got two issues, one regarding to real-time and another
regarding to freewheeling mode aka faster than real-time?
For my Terratec Envy24 cards JACK1 doesn't work, only JACK2 does, I
didn't test JACK1 with my RME card until now. I don't claim anything
else about JACK1 and 2, but that there are issues for my Envy24 cards
too, when I use JACK1 on my current machine for real-time.
Perhaps you can use Jack2 + the hints Jörn gave, to fit too your needs?

joerg, just a shot in the dark: are you runnning jconvolver? it
to barf in freewheeling mode, for some people, under some
in any case, as a temporary workaround, you could use
record your session in real time, or alternatively bounce to
ardour stereo track and then convert those files to your desired
format on the command line (sox -M or "merge" is your friend).

ralf, these guys are talking about export, which runs in
mode. there are no xruns in freewheeling mode. stop spreading
