No problem - just set the normal one as the standard soundcard
(primary device). The second one will only be used if the first one is
already occupied (this is unlikely to happen under win98 and later) or
when you select it by hand in the output options of your sound
playback programs...
You can also have 3 or more installed cards as well - if you manage to
have enough slots and ressources left
