I have a Pinnacle PCTV pro with a bt878 chipset. I downloaded the latest kernel (2.4.10), and built the bttv drivers as a module. When I watch TV with Xaw/FBTV I get audio through the line in on my soundcard, but when I capture tv (vcr, nuvrec, ffmpeg) I have to move the audio patchcable to the mic in input or I get no sound. Am I missing something very simple here?
