One thing that may give you trouble is that the order of the two
cards may change, with the new card being sound card 0, and the
existing one being sound card 1. You may have to use the index
option in /etc/modprobe.conf (or /etc/modprobe.d/<file>) to fix
this. You probably have something like "options snd-card-0 index=0"
in the current file. You should back up your modprobe.conf file
before adding the new card.

ANother thing that could give you trouble is if the current sound
card is built into the mother board. On some mother boards, the BIOS
can be configured to disable the built in sound card when it detects
another sound card.
