So you need 2 different drivers for your soundcard. One of your 2 soundcards should have 2 different drivers that will work on each individual install.
So post up your soundcards and lets see what drivers we can find. Also what verisons of xp and win7 are you using? 32bit or 64bit for each.
I would do this, if you're using the sound cards in a dual-boot single computer configuration. If you're using 2 different desktops, and say a KVM setup, you can use a 3.5mm Y splitter with 2 males and 1 females plugs. RadioShack, BestBuy, Staples, Walmart, ect. ect. should have these cables too.
