You need to turn on monitoring for the Delta card so you can hear what
you are recording.  This has nothing to do with Ardour or Jack... you
will need the envy24control utility that is bundled with alsatools. 
If you set the tool to use the digital mixer, you can use the
zero-latency monitoring the card provides.  Oh, yeah, make sure you
have software or hardware monitoring turned OFF in Jack and Ardour,
because it will cause strange things to happen if you are using the
envy24control monitoring.
