Assuming that your tuner card doesn't do hardware encoding, you should
have sound for livetv because of the sound being embedded in the raw
/dev/video stream. But, i'm gonna guess that for you, recording does it
differently, by taking the video from /dev/video and audio from your
sound card's line in.
thats just a thought.
