Hi, now I had time for some tests.
options snd-ice1712 index=0
options snd-usb-audio index=1,2,3
options snd-virmidi index=4
But I have another problem. I only have three sound cards, not four.
One audio card, DSP2000 and two usb cards for midi, Midisport 4x4 and a
master keyboard UF6
But in /proc/asound/cards is another usb device which I don't know. It is
the last one.
cat /proc/asound/cards
