The driver tried to load at index 0, but another driver already has it:

You have *three* USB audio devices; and all settings for one module must
go into one line:

  # options snd-usb-audio index=1,2,3

However, instead of that, there is a better option that allows you to
set the order correctly even if additional devices appear:

  options snd slots=snd-ice1712,snd-usb-audio,snd-usb-audio,snd-usb-audio,snd-virmidi

To set the order of the USB devices, read the vendor and/or device IDs
with lsusb, and give those to the snd-usb-audio driver with the vid/pid
options.  This line sets the MidiSport first and the unnamed device
second:

  options snd-usb-audio pid=0x1020,0x2202
