First This cannot be done is CRAP! IT can be done. But i am not a VC++ + directx programmer so i coldnt write a program to do so, so i have to do that manually. here is how.

get graphedit : This is a Free tool to test directshow graphs.

1.Add filter manaully , You will need sound card input filter to choose input source.

2.Some directshow filter you have like AC3 codec or other upmixer or audx.

3. Select your soundcard as renderer.

Connect theese modules and save the graph.
Hit play in graphedit to start processing and you can hear your incoming line in on soundcard via upmixer. fiddle around it's matrix to route your line signal whereever you want. If you want to use your cards own filters etc , check in filters if they are supported as directshow and you can do anything there.

regards & good luck.

BTW: i have been watching my tv via AUD-x upmixing since i came with graphedit idea. tv viewing has never been better.
