Hi Barry,
Yes, built-in sound cards "work," but my extensive testing showed that a
good outboard USB sound card works FAR better than the sound built into
my Thinkpad laptops. The difference is the ability to decode much weaker
signals. That testing is documented in the link I posted yesterday.

The Asus cards are about $60-$70 and my Steinberg was $120. It makes
no sense to spend that amount of money for a card for an application
that will work just fine with your computer's built in card. However,
you will need some additional "stuff", like isolation and a PTT method
if you don't use vox. That is why I recommend that something like a
SignLink USB, or equal, be used. To go some other way, the bottom line
costs will run you more than than either card to do it right. And, yes
there are really cheap cards out there for $20, but they just won't
perform for spectrum viewing.
