Sounds convincing.

Tim, you could try to use the additional "id" option, instead of pid.
(I didn't try that myself so far.)
Assuming, the id is different, for each device, of course.
Is it ?

for example
  modinfo snd_ice1712
or
  modinfo -p snd_ice1712
tells me, that the parameter id is supported:

  parm:           id:ID string for ICE1712 soundcard. (array of charp)


The options line would then look as
options snd-ice1712 index=1,2 id=0x0033,0x0044
