Thanks Calum!
Does that mean, problem solved then?
At least, the problem you were asking about originally?
As for your other problem, the link honvetops provided looks very useful to me.
I myself am not sure about this, my card is rather different.
Because it is so small I have only 3.5mm audio out and mic in, I do have another thing that plugs in with three more jacks.
I gathered that was for surround sound, so I paid it no further mind and have never used it, therefore I can't help you.
