Will you upload and link to a screenshot of your setup in qjackctl, please?  What you've described is exactly what I want to achieve.  Also, what version of jack are you using? For me, it just doesn't work and I've tried many different configurations and permutations :P Thanks!

In qjackctl settings you can pick a seperate soundcard for input and output, I do this and use my laptop's onboard for playback and an external usb for recording at the same time. </blockquote></div>
