I'm experiencing problems trying to run my Line 6 UX1 particularly in Ardour and Guitarix. Through JACK, I'm able to start it and run it with seemingly no problems. However, it only picks up the Mic Input. So I could record with the Mic but nothing else. In Guitarix, I'm still not able to get anything out from my 'instrument' input, which, in this case means my guitar.

Has anyone else experienced problems like this?
