[linux-audio-user] capture problems

I had to send my Audiophile back because it did not come with the breakout cable, so while I am waiting for the new card to come I figured I would experiment with the onboard sound (nforce2) and test the waters a little. But I am having a problem capturing audio from it. If I connect an audio source to the line-in, I can hear it playing through my system. Then I start qjackctl and get jack going. Then in ardour, I create a track and connect it to the alsa_pcm capture, but there doesn't appear to be any signal coming in. I have recorded from other jack clients (Hydrogen) so I think I have that part figured out, but the capture is not working. The whole time, I can still hear the audio source through my system. Should I be hearing this? If I look at the jack connections, there is no connection between the alsa_pcm capture clients and the alsa_pcm playback clients. Sorry for the noob questions, but I have never tried to capture audio before. I promise once I get up to speed I will be on the other end (helping out ;-)
