Could it be a digital signal causing the problem?

Subject: Recording on SB Live line-in
I can't record the audio I hear when I plug my VCR or stereo into the
line-jack on my SB Live sound card. I can record if I plug it int the mic
jack but the quality isn't as good. I've used aumix to set the level of
the line-in to 64 which sounds good. But recording with sox gives me
nothing but silence. Ie:
$ aumix -l 64 -m 64
$sox -t ossdsp /dev/dsp bogus.wav
That works if I have my VCR connected to the mic although the quality is
poor. Can I tell it to record from the line-in but not from the mic? Maybe
aumix isn't the best tool to use.
Alternately, maybe I could get the mic to work... The problem with the mic
jack is that I get only the left or the right channel. I have a cable with
2 RCA jacks on one end and a stereo jack on the other. The 2 RCA jacks are
plugged into the line-out on the VCR, left and right. The stereo jack is
plugged into the mic on the sound card. Only 1 of the RCA jacks matter. The
other I might as well leave dangling because I don't hear that channel no
matter what. I can get the left channel on the VCR if i plug the jack that
works into the left line-out jack on the VCR or I can get the right channel
by plugging it into the right line-out jack. So the mic is acting as if
there's a stereo-mono converter in there somewhere.
I know the cable is good because:
1. I can hear both channels if I plug it into the line-in on the soundcard.
But as I explained above, then I can't record.
2. I have a second cable and that one does the same thing
3. Both cables work fine with another sound card
