Good question.  I've just run into something similar myself, and haven't 
sorted it out yet.  It was all working a few days/weeks ago.  I'm not sure 
what broke.  Maybe when I figure it out I will have a clue to offer you.

Without knowing absolutely for sure, I'd think not.  I think the library 
Rosegarden uses to handle that sort of stuff can do such conversions 
automatically.

You really do, yes.  JACK doesn't run worth a crap unless you use a realtime 
kernel.  I tried to resist for a very long time, and resistance was futile.

The root thing probably has something to do with "capabilities."  You need 
"capabilities" so you can run JACK in realtime mode as a user.

No time to go look up details at the moment, and I don't remember the details.
