I've gotten the UCG102 working under Ubuntu 12.10, using qjackctl and rakarrack, but had issues with latency. So I thought I'd try out Ubuntu Studio from the livecd. And I can't get it to work. Any help would be appreciated.

I'm guessing that if I could just connect everything correctly I'd be fine, but I just can't figure it out. I see that after I configure and run jack using qjackctl, and then run either rakarracl or guitarix, that lots of connections get made. But neither gets a signal from my guitar. It does get input from the builtin microphone of my computer (Thinkpad 420s FWIW).

I'd really appreciate any help getting this to work! Does it have anything to do with ubuntu studio's using pulse audio?

Here's a bit more info in case it's of use.
