> i have a firewire interface that i use on my production machine, and some
USB devices, but i have found that those device identifiers can jump around
when using devices with JACK that use the same driver. i have found that
those numbers have jumped around for a long time (i noticed this was an
issue first hand in 10.04). when providing support, i usually suggest to
folks to disable the internal sound card in the bios (assuming that is a
possibility, and i guess its not for you). there were several "solutions"
to this challenge discussed in the #opensourcemusicians channel on freenode.
