Okay, I had a sound which was working fine - then I decided to upgrade to the Xfi Music Card. However, after installling the card - disabling the onboard sound after having problems. I tried again - no difference. What the error message says is that no "registered product" can be detected. Eventhough I don't see any reson for it to not be.

I know where device mangager is but what am I looking for?
. Then sometime yesterday I did receive sound for a few minutes then it dissapeared again. I also ready about interference from wires, so in a bit I am going to have a go at removing wires from anywhere near my sound card.
