OK, let me see if I understand you.  There's no way to get at audio (in
digitized form) through the PCI bus, so you have to route the audio out on
the card to an audio in on your sound card and get the digitized audio
through the PCI bus on your sound card.  Am I right?

I know I'm being a pest about this, but I'd like to eventually have multiple
TV tuners in my MythTV system.  I wanted to use the Leadtek tuner because of
its low price and its stereo sound, but now I'm not sure if it will work for
me, because I'll need an audio in on my sound card for every TV tuner,
right?
