You don't need btaudio.  Does your capture card have an audio line-in?  
It should.  Plug the sound output from the DirecTV receiver into your 
capture card's line-in; connect the capture card's line-out to your 
sound card's line-in.  Assuming you have your sound driver/mixer set up 
correctly, this should work.  Your capture card should switch audio 
sources along with the video source; so when it switches to the 
composite input for video it should also switch to the line-in for 
audio; when it switches to the tuner (coax) input, it should get both 
audio & video from it.

Incidentally, this doesn't work for me on my WinTV-radio PCI (401) card.  
When I switch to my S-Video input, I get either no sound or crossover 
sound from the tuner.  I've posted to the list about this, but no one 
has reported a working setup like this with a WinTV 401.  One other 
person reported the same problem as me, but I don't believe he ever 
solved it either.  I've got 2 M-179s waiting to go into my machine, so 
I'm not overly worried, but I'd still like to figure out the issue...

Anyway, hopefully you won't have that problem with your card.
