I have a WinTV card that uses the snd-bt87x module and if I remember I
had the same problem originally.  Here is the relevant portion of my
modprob.conf:

##########

### Onboard sound to dsp0
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0
remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ;
}; /sbin/modprobe -r --ignore-remove snd-intel8x0

### Get sound from WinTV to dsp1
alias snd-card-1 snd-bt87x
options snd-card-1 index=1
options snd-bt87x index=1
remove snd-bt87x { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-bt87x

##########

Note that the 'remove snd-bt87x...' line may be wrapped but it is
indeed one line.  I am able to get sound directly off of the card
instead of looping it to the sound card input.  HTH.
