Yup!  That was a huge help!  Thanks :) Biggest difference is that I was using specifics (like hw:1,0) instead of the general interface (hw:1).  Probably explains it all. How are your xruns with this setup? Thanks again Joe!  You're a lifesaver!!

There is a screenshot <a href="http://adam-a.co.uk/jack-setup.jpg" target="_blank">here</a> of my setup. Important things are highlighted: in blue, use the '>' buttons to select a different input and output (mine were 'hw:1    XioSynth' for input and 'hw:0    Intel ICH6' for output). And in red, I had to set periods/buffers to 8 otherwise jack would crash, this may be different for different devices though. </blockquote></div>
