I have the same issue with the GUI not showing up on some starts...thought that has been addressed recently (there's been something in the changelog), but seems not to fix it.
For the audio device, you should be able to use the ALSA name, I have a RME card and it identifies as hw:HDSP. You can tell the names by typing aplay -l and aplay -L on the command line.
Thank you for your answer! Yes I know how to find the names. The problem is the Juli@ card just keeps changing at every boot from hw0,0 to hw1,0 or vice versa as I said. I don't know how to fix this and cannot find anything about it on the internet. Seems to be some kind of alsa issue since there are no 'two' inputs on the Juli@...
