Is the card capable of outputting digital audio? Maybe a card that is 
able to toggle the output port between digital and analog audio? Perhaps 
it's sending in digital right now when it should output analog?

I haven't fiddled with sound much either, since this is a feature that 
has usually "just worked" for me as well. But I did get static in my 
earphones some while ago when I had accidentally unmuted the "digital" 
channel (and hence effectively toggled the output to audio).

Might want to look into it :)
