hmmm. I'm using a HDSP9652 - I think it supports hardware monitoring and I
did try it (jackd -d alsa -H right?)

Monitoring doesn't matter all that much, and I was doing #3 - but it's
actually RECORDING late (I was working around last night by sliding the
audio region back after recording) there's a delay before it gets there.
hmmm it may be because I was using -p 2048 - I needed to do that when I was
first trying to run ardour, but maybe I don't need to now - i have changed
soundcards, kernels and alsa drivers since then ;)

my jack command line was:

jackd -R -a -d alsa -d hw:0 -r 48000 -p 2048 -H

hmmm
