Hello,
I have problem that I've been trying to figure out with no luck.  The
audio interface keeps changing for example:

Today:  Maudio 24/96 is hw:1 and Midisport 4x4 Anniv is hw:0.
Yesterday before reboot: Maudio 24/96 is hw:0 and Midisport 4x4 Anniv is
hw:1 etc, back and forth, each reboot...
I usually use qjackctl and have to keep changing the presets with
settings which is annoying.

I would greatly appreciate it if someone could provide me some clues
or links on how to fix this?

I'm Using Fedora 12 w CCRMA.
While you can force the order with the proper index=xx incantations in
modprobe.d/ files, that will fail if the computer is booted with a usb
sound card attached.

The proper fix is to not use the index (a number) when addressing the
card but use the name of the card. That will never change across
reboots. So, instead of "hw:0" use "hw:NAME" where NAME is what is shown
between square brackets in the output of cat /proc/asound/cards

Does this solve the identical sound card problem in any way? Say two identical usb sound cards at the low and and two delta 1010's a little further up the chain as examples.

Hmm, IIRC, can't you use the alias option to assign a name to a specific soundcard?
