What about using alsa_in/out to pipe Rivendell into Jack?
You can keep Rivendell with plan ALSA, working at 44.1 or 48 kHz. Then
create an instance of Jack server at 192kHz. You can plug what goes out
from ALSA into Jack by launching alsa_out. I think it can resample on the
fly so you should have it working.
Not sure it's a safe/stable solution.
Just give it a try, I'm curious!
