Does the Interface list widget in qjackctl Setup turn gray (disabled)
when you select input and output devices that are not the same
soundcard?

Just to clarify, you need the following connections to record into
Ardour and hear what Ardour plays:

System Out connected to Ardour In.  Ardour Out connected to System In.

When you record in Ardour you should see the guitar waveform.

When you play back the recorded waveform or an imported audio file in
Ardour, you should hear it from your PC speakers.

Do either of these work?
