I am no alsa developer but this this worked on my openSUSE installation...
You edit your /etc/modprobe.d/sound to force which sound device belongs
to which card number.
In my case this looks like:
options snd-ca0106 index=0
options snd-usb-audio index=1
Where the SoundBlaster Live! 24 Bit (ca0106) is set to card 0, the
default card.
The Roland UM-1 usb midi interface (usb-audio) is set to card 1
Use the terminal command cat /proc/asound/cards to find the snd-xxxxx
driver names, in my example
simon@simons-pc:~> cat /proc/asound/cards
0 [CA0106 ]: CA0106 - CA0106
Live! 7.1 24bit [SB0410] at 0xdc00 irq 5
1 [UM1 ]: USB-Audio - UM-1
EDIROL UM-1 at usb-0000:00:07.3-2, full speed

On rebooting your PC the sound cards will be sorted in the desired order.
Ciao, Simon
