OPTi EV1935 MachOne soundcard

My motherboard has AC97 audio built-in. I just stuck an old OPTi EV1935
MachOne soundcard that I had lying around into the machine. Kudzu did
not alert me to new hardware at startup, but it did put an entry into
/etc/sysconfig/hwconf. lspci also shows the card (and identifies it
correctly).

I cannot figure out how to get anything to actually use the card. The
volume control, soundcard detection, hardware browser, etc applications
don't show it. No audio players give me the option of using it. Other
than /etc/sysconfig/hwconf and lspci, I haven't found anything that
seems to even know it's there.

My questions are:

1 - How do I get this card to work?

2 - Is it possible to use both the motherboard's AC97 and the soundcard
at the same time (application A using one, application B using the
other)?

3 - This one's a bit OT here, but does anyone know how this card
compares to the built-in AC97? Which one's better?


Here's the lspci -v output:
