I've got an archlinux box that I'm using for a DVR; capture cards are a Hauppauge PVR-350 and a pcHDTV 5500. Right now I only have analog cable, so I'm using the 5500 in analog mode. There is a cord that goes from its S-video output to the line in on the back of the sound card. This is supposed to allow me to use the audio.
Alsamixer is set, alsa used in daemons to reset on reboot. The line out from my sound card goes to the amp that runs the sound on my tv.
When I boot the machine, all is well, and I go to Mythtv to watch tv. The 5500 is the primary card for that right now. If I watch tv, all is well, audio and video. When I stop, the audio does not stop. I can leave mythtv, even leave X; the audio continues.
Why would line-in continue live at all times after it comes on? I'm sure I'm missing a setting somewhere, but can't figure out what it is. Any ideas?

Ok, I solved that... My sound card had a number of settings in alsamixer that apparently are not common, so I had to experiment a lot. I ended up having to mute the line in and front inputs, then set the outputs to Mixer; that ran the audio through mythtv instead of straight through from line in to line out and then to the tv.
