If you don't really need it's super-duper extra functions like
gaplessly moving a stream from one sound card to another you better

I don't have a solution for the original question, because I don't use
two sound cards at the same time, but there are other and better ways to
disable the internal notebook speakers.

Usually you can choose in every application which sound card to be used
(sometimes in it's config files). I guess there are software mixers for
every desktop environment which let you choose the sound card, which
shall be used.

Btw., isn't there a button on the notebook which can mute those
