I have tried to help several people fix card and driver problems.

I will say this, Microsoft, in dealing with systems that they feel have improper versions of XP, have a back door way through updates that can cripple the device drivers for sound cards.

Both the systems I looked at were ones that the owners failed to move properly from system to system, and were on the net.

No amount of tinkering with the computer that worked fine yesterday would solve the problem. Both the systems were 'older' and had run for years with the cards, and boom, they didn't.

Both owners bought new computers with OEM Win 7 and darned if the same old card didn't work out of the box. Odd eh? But both had had messages, "This may not be a valid version of windows." Then they quit working.
