I think that we, end users, want the following:

* we want to be able to disconnect/reconnect external cards;
* we want to be able to use (crappy) internal audio chips for things like
Internet telephony;
* whenever we disconnect/reconnect external cards, we do NOT want to adjust
ALSA configuration files - especially taking into account difficulty creating
them.

So, the mechanism should allow to assign to cards indices once and for all -
regardless whether the card is present or not.

Can the indices be non-contiguous ?

Can we load external card driver even if the card is not present ?

Do we need to load external card driver even if the card is not present ?

Thanks,
  Sergei.
