I am sure there are other answers to your dilemma, but anyway, my take
is that the 1010 cards were really designed to be used with something
like JACK or a similar technology - i.e., there are multiple sound
sources, multiple destinations, and you're routing between them with
JACK or something like that.

I have the 1010 full version, I'm using Fedora Core 5. I simply
connected the studio monitors (the speakers) to the outputs #1 and 2 on
the 1010. Without JACK (e.g. when I'm watching a DVD, or listening to
music via XMMS), all applications just "do the right thing" and send the
signal to those outputs. But when I use the music equipment, I fire up
JACK and I use it to make the proper routings.

So, in my opinion, stereo apps sending output only to #1 and 2 (in the
absence of JACK) is normal. If you want more complex routing, just use
JACK.
