When I tried this I got a nasty ground-loop hum on the cable.
Soldering in a 10k resistor across one of the lines in the cable seemed
to get rid of it without disturbing the sound quality. I think I knew
why that worked at the time, but I'm no EE... I was using a
SoundBlaster 16 which wasn't the best quality, so perhaps that had
something to do with it.
Anyway, a $3 fix if you run into it.
