moninfo cx88-alsa

... this will show you a module option called, 'index' ...  if you pass
'index=1' to cx88-alsa, then it will use the 2nd minor, instead of the first.

A much better practice would be to instead, pass 'index=0' to the module that
actually drives your sound card.  use the modinfo command to check that the
option is available.
