In our home media center, we have a desktop that is hooked up into our reciever over a coaxial digital connection. This works questionably well, (using a xp driver under vista, I can get the card to work in 2 channel pcm mode, but ac3 has proved quite the challenge) but isn't my biggest problem.
We are trying to get it set up so that we can listen to the cable box, while having the source on the reciever set to the computer. We can make it work by setting the cable box to use the digital output from the cable box as the audio for the computers video source, however doing this makes it so that in order to hear the computer, you need to change the settings on the reciever, which is a pain.
So to solve this problem, I have taken the analog output from the cable box, and connected it to the line in on the computer. This connection is working, and I can even record the cable boxes audio in cooledit.
Unfortunantly, vista isn't smart enough to realise that the hardware mixer on the sound card (turtle beach santa cruz btw) isn't going to work since I am not using the analog output from the card, and it refuses to play the line in over the digital output from the card.
I can record the line in, and then play it back using software like audacity, but that isn't very useful while trying to watch tv.
I also tried connecting the line in from the cable box to the onboard sound card,hoping that vista would then realise that it needed to do the mixing in software, but still no luck.
Does anyone know of a piece of software that will loop the line in out the standard sound system (like pretends to be a normal program)? I was considering doing something like setting up a shoutcast server and having winamp playing the stream, although there would probably be considerable delay from the buffering.

I think the problem is that the hardware mixer on your soundcard is analog.
There's no easy way of looping it digitally that I know of, without incurring the latency of the Windows sound system, which can be hundreds of milliseconds.
If the latency isn't too bad, you could look to see if Cool Edit or Audacity have a monitor function.
Or maybe you can use Winamp as a loop-through. I know it has a Line-in plugin to let you drive the visualization from another source. It can also output through DirectX which would help the latency.

The winamp linein plugin worked great, at first there was a large delay between the video/audio, but i set all of the buffers for the directsound output to 0ms and now it works great
