Hi James, I suspected at least part of the problem was crappy timers. I set Jack up to 4096x4 and it was a hundred times better, but still had a xrun every few seconds.
I've been playing around with it some more and I think the USB Audio device is a big problem too. If I change Audacity to use ALSA and the normal audio card, it works okay. I think maybe I will go back to just running Rivendell on the host OS and forget the VM idea for now.
