HTH. 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
